Trade activity to urbanization, trends driving the future of rail industry

Over 50 tons. This is the amount of goods transported annually, per person in the U.S. This shouldn’t be surprising given the device you are reading this article on is likely made from several different minerals and multiple sub-components. These get mined or manufactured at different locations then transported to various locations in-between, before getting shipped to you. 

The transportation sector is one of the pillars of our modern world, and rail is a critical component of this eco-system. This article spotlights a few trends impacting the future of the rail industry to help your organization succeed and keep your perspective of the future fresh with these insights. Let’s look at these three trends influencing the rail industry this decade.

No. 1: An urbanized world needs more efficient ways to transport people

It may be difficult to imagine that only a third of world’s population lived in urban areas just a few decades ago. In comparison, more than half of world’s population live in urban areas today. 

There are good underlying reasons for urbanization: people move to urban areas to prosper, find better jobs, and to get access to education and health services. Meanwhile, urbanization also has its damaging side-effects; we live in urban areas where some face water and air quality issues, poverty and limited housing. When it comes to transportation, congestion and the environmental impact are commonly called out as two side effects of urbanization.

On the bright side, emerging technologies in the energy sector combined with advancements in connectivity help us create more efficient transportation solutions. These include electric buses, autonomous cars and of course, modern trains.   

Modern trains feature innovations such as the use of renewable fuels, sensors and IoT devices. These enable autonomous operation, increased safety and a reduced carbon footprint. Moreover, rail transportation continues to offer the highest capacity per hour to serve people’s travel needs in a transitway setting 1.

Going forward, urbanization is expected to increase the demand for rail transportation within and across urban areas.

No. 2: Expanding middle class consumes more; increasing the transportation of goods

2018 was the first year 50 percent of the world’s population had enough discretionary spending to be considered “middle class” or “rich,” according to The Brookings Institution 2

There are two sides of this story. On one side, the middle class is under pressure with weakening job security and stagnating income levels. Moreover, the on-going COVID-19 pandemic puts increasing strain on our economies. On the other side, a growing middle class means increasing the number of people with higher purchasing power. This results in increasing trade activity and traffic of goods.

Think of how frequently you replace your electronic devices and the extensive supply chain behind these simple purchases. Minerals to be transported to mills to produce metals. Then these metals get transported to factories to produce goods. These goods get transported to warehouses, then to consumers. Trains have long been a critical component of the transportation eco-system that facilitates this freight movement. 

Going forward, the continued expansion of the middle class is expected to fuel the growth in the rail industry when it comes to freight transportation.

No. 3: Our environmentally conscious society demands greener modes of transportation

Seventy-five percent of the respondents to a PEW Research Center survey were particularly concerned about helping the environment 3
The transportation sector gets the spotlight when it comes to helping the environment by reducing greenhouse gas (GHG) emissions. This is partially because the sector produces 15 percent of man-made GHG emissions globally, and is second only to the electricity and heat sector 4.

Rail has long been considered as one of the most environmentally friendly modes of transportation both for goods and people. In fact, it is estimated that rail moves 40 percent of freight measured in ton-miles, but is responsible for only 8 percent of freight transportation carbon emissions 5. Meanwhile, there have been significant advancements in road transportation over the last decade to lower environmental impact. These advancements range from trucks powered by hydrogen fuel cells to buses powered by fully electric drivetrains

The rail industry is also reducing its already low environmental footprint. Trains powered by electricity supplied through overhead power lines have been in use for a long time. Nowadays, some of these trains produce zero carbon emissions when the electricity used is produced by renewable sources. There is also growing interest in powering trains with hybrid solutions featuring hydrogen fuel cells. In fact, Coradia iLint, launched in France, is one of the first passenger trains powered solely by hydrogen fuel cells and produces zero emissions at the point of use. 

It is an exciting time to be in the rail industry where the macro drivers such as an expanding middle class and urbanization increase the demand for the industry’s services. Moreover, societal changes coupled with emerging technologies in energy and connectivity create the room for the industry to transform itself into a high-tech sector.

Cummins dealer co-op program helps WWII Veteran

When the Arkansas Veterans Administration (VA) contacted Cummins dealer, Northside Power, about providing a generator to a local WWII Veteran – Northside Power didn’t hesitate.

“We feel this is one of the simplest things we can do to honor someone who gave their time in service to our country during such a trying time in history,” said Greg Nalley, Owner of Northside Power. 

James Joseph Torres (Jim), 93, was born on May 23, 1926 in Pine Bluff, Arkansas. Shortly after graduating high school, Torres was drafted into the United States Navy at the age of 18. “I was 1 of 700 people drafted that day,” recalls Torres, “They just told me you’re going to the Navy.” Torres was soon sent to San Diego, California for naval training where he was trained as a fireman. During his three-year enlistment, he would spend most of his time on the U.S.S Massachusetts sailing to different ports all over the world including the Philippines, Hawaii, and the Panama Canal. 

After three years in the Navy, Torres transferred branches and enlisted in the Fourth Army where he served as a Corporal in the 1040 Squadron at Fort Sam Houston in San Antonio, Texas. There Torres set up a M.A.S.H medical unit used to train medics and nurses that were being sent to the Korean War. While working at the Brooke General Hospital at Fort Sam Houston, Torres managed to catch a glimpse of the famous General Douglas MacArthur. “He was walking through the hospital smoking his pipe,” remembers Torres. 

After six years in the Army, Torres enlisted in the United States Air Force, where he trained to become a crew chief on the B-52 bomber. “I scored the highest out of all the candidates on the test that day,” said Torres. He was subsequently stationed in Shreveport, Louisiana at Barksdale Air Force Base and retired in 1966 with the rank of Master Sergeant/E8.

Cummins continues to be a strong supporter of the US Armed forces. Supporting veterans aligns with the company’s core values and beliefs. Through the years, the company has provided power solutions to our troops in the field, as well as, mobile power solutions for military vehicles.

After learning that Mr. Torres was in failing health and did not qualify for additional services through the Veterans Administration, Northside Power and Cummins felt compelled to help. Using funds from the Cummins Co-Op Policy program, Northside Power was able to install the Cummins QuietConnect Series generator at no cost to Mr. Torres.

Five practical tips to keep your facilities and business on through potential power outages

Keep business running through a power outage

Healthcare services, water plants, data centers, greenhouses, food manufacturing and textile facilities producing personal protective equipment (PPE), all play a key role in overcoming the current pandemic. These industries also have another thing in common; uninterrupted access to electricity is critical for the continuity of their operations. 

Fortunately, resiliency and flexibility in our electricity infrastructure is expected to prevent any large-scale blackouts. Moreover, these facilities are also commonly equipped with on-site back-up power generation systems. These systems keep these critical facilities running if the utility power goes out. 

This article outlines five practical maintenance tips for your business’ back-up power system. These tips aim to address preventable and inspectable issues, and are complementary to your scheduled and unscheduled maintenance procedures, not substitutes to your existing procedures. 

No. 1: Regularly exercise your back-up power systems 

Regular exercising helps with reliable engine starting. It keeps engine parts lubricated, prevents oxidation of electrical contacts and uses up fuel before it deteriorates. Exercise your generator set at least once a month for a minimum of 30 minutes loaded to no less than one-third of the nameplate rating. Try avoiding periods of no-load operation, since unburned fuel tends to accumulate in the exhaust system. One testing option is to simulate a power outage by conducting the test with your facility’s load. Alternatively, you can use a load bank during testing if connecting to the facility load is not convenient for test purposes. 

No. 2: Ensure there is adequate fuel; confirm fuel quality 

Start by checking the main and day tank fuel levels to ensure you have enough fuel to operate as needed. Continue your visual inspection by checking for any leaks, cracks or loose connections. Tighten the clamps as necessary. Inspect the day tank float switch; it ensures the day tank is getting filled from the main fuel tank, as the fuel level within the day tank drops. Drain any water or sediments from the fuel system if necessary. Diesel fuel, when stored, is at risk of contamination. Exercising the generator set regularly is one way to address the contamination risk, since the fuel gets used through this planned exercise. NFPA 110 recommends testing fuel quality at least annually to ensure stored fuel has not degraded significantly and to identify treatment opportunities. If there is need, you can consider fuel polishing and tank cleaning. 

No. 3: Confirm that starting batteries are sufficiently charged  

Weak or undercharged starting batteries are the most common cause of standby power system failures. Begin with a visual inspection of starting batteries. The connections at the terminals need to be tight and clean of any corrosion. You can clean the batteries by wiping them with a damp cloth. Corrosion at the terminals can be cleaned with a solution of baking soda and water. Finish up by checking the electrolyte level and specific gravity. Fill the battery cells with distilled water if electrolyte levels are low. If the specific gravity reading is below 1.215, charge the battery. You can also check whether the batteries have recently been replaced; batteries should be replaced every three years.

No. 4: Regularly inspect and test power system transfer equipment

Transfer switch equipment generally requires limited maintenance, compared to power generators. Start by verifying all indication lamps are functional, and the control switches are in the proper (AUTOMATIC) position. Check circuit breakers and fuses to ensure they are free of dirt or corrosion. If your facility is required to be NFPA 110 compliant, test the transfer switches at least once a month. 

No. 5: Conduct daily visual inspections of your back-up power system

A simple daily walk around your back-up power system could help you identify preventable issues before they lead into loss of life, personal injury, property damage or loss of business income. Conduct a daily visual inspection including, but not limited to:

  • Check for oil and coolant levels.
  • Check for any debris, loose or broken parts; check if there are any leakages.
  • Check the operation of the engine coolant heater(s). If the engine block is not warm to the touch, the jacket water heaters are likely not working and the engine may be challenged to start.
  • Keep the area around the generator clear; do not store items around or on top of the generator. 
  • Make sure the generator and automatic transfer switches are locked 

Please ensure to follow the schedule in the operator’s manual for routine periodic engine and generator maintenance in addition to these practical tips. Many of the tips in this article are adapted from the following resources that you can check for further details.

Energy IQ: Twenty energy terms described in 50 words or less

Energy IQ - Energy terms defined

You have questions about energy, we have answers. In our latest Energy IQ article, we take a stab at defining 20 energy-related terms in 50 words or less. 

Energy is the cornerstone of our lives. We often use six different forms of energy within the first hour of our day. Washing your face requires electric energy to be converted to kinetic energy within the water pump. Using the stove to cook breakfast converts the chemical energy within natural gas to heat (thermal energy). Turning on the TV converts electric energy to light and sound, two more forms of energy.

In our latest Energy IQ article, we've attempted to describe 20 common energy terms in 50 words or less. You might be aware of some of these, yet some might be relatively new for you. 

Let’s start with the basics. Here are three key words that are used quite frequently: Energy, electricity and power. 

What is energy? 

Energy is the capacity of doing work. Energy can’t be created or destroyed, but only converted from one form to another, according to the first law of thermodynamics. There are nine forms of energy, and we convert energy between these forms to get the needed work done.

What is power? 

Power is the time rate of performing the work. As you apply power (watts) over time (hours), energy is consumed (watt-hours). Many devices generate power; a diesel electric generator produces power by converting chemical energy to electricity, and a solar panel produces power by converting the energy of sunlight into electricity.

What is electricity? 

Electricity is simply one of the many forms of energy and is created by the movement of electrons. The ease of distribution and the ability to use it safely makes electricity a popular form of energy in our lives.

The simple experiment outlined in this article will help you never forget the difference between power and energy, and details the differences between energy, electricity and power.

Many technologies and components work together to bring us the energy, power and electricity we need. Let’s start with the system level terminology before covering individual components.

What is distributed generation?

Distributed generation is an interconnected ecosystem of smaller power generation systems at or close to the point of consumption. This proximity reduces the cost, complexity and inefficiency associated with electricity distribution. Distributed generation also offers the benefit of reduced emissions through the integration of renewable sources with existing energy assets. 

What is a microgrid? 

A microgrid is a local energy system capable of producing, (potentially storing) and distributing energy to the facilities within the network. Microgrids can include several different assets, also called distributed energy resources (DERs). You can read how microgrids work, why we need microgrids and their advantages in this article. 

What is a microgrid?
Microgrids provide energy through distributed energy resources (DERs) and are near the facilities they power. 

What are distributed energy resources (DERs)?

Distributed energy resources (DERs) are electricity-producing resources connected to the local electric distribution system. Solar photovoltaics (PV), power generators, fuel cells and stationary energy storage systems are some of DER examples. You can read more about three common use cases and deployments of distributed energy resources in this article. 

What is a smart grid? 

Smart grid refers to modern electric grids where a mix of technologies that enable two-way communication between the utility and its customers. Controls, computing equipment and other digital technologies work together as components of the smart grid to increase the reliability and efficiency of the electric grid. 

Let’s now move into individual components that work together within the broader energy eco-system.

What is a power generator? 

In electricity generation, a power generator is the device that converts mechanical, chemical, solar or other forms of energy to electricity. The electricity then can be used to power buildings, facilities, homes or mobile applications such as recreational vehicles. 

What is a fuel cell?

Fuel cells are energy converters; they convert energy from one form to another. More specifically, fuel cells convert the chemical energy stored in the fuel to electric and thermal energy (heat), without the need for combustion. You can read more about fuel cell basics in this article

What is a solid oxide fuel cell (SOFC)? 

A solid oxide fuel cell is a type of fuel cell; it produces electricity, water, heat and small amounts of carbon dioxide. SOFCs can operate at high temperatures, so the system can cope with hydrogen reformer and use natural gas as the fuel. You can read how solid oxide fuel cells work and their advantages in this article.

What is an energy storage system?

Stationary energy storage systems store energy and release it in the form of electricity when needed. An energy storage system usually includes batteries, a control system, inverter and thermal management system in an enclosure. You can read how energy storage systems work and advantages of energy storage systems in this article

What is an automatic transfer switch (ATS)? 

Automatic transfer switches (ATS) switch electrical loads between available power sources. Most often, ATS are used to transfer the electrical load from the utility source to a back-up power generator during a utility power outage. ATS reconnect the load to utility power when the utility power is restored.

Often, electricity generation is simultaneous with the generation of other forms of energy. This simultaneous operation reduces wasted energy and increases energy efficiency. Let’s cover the terminology associated with these energy efficient applications. 

What is cogeneration, also known as combined heat and power (CHP)?

Cogeneration is the simultaneous production of multiple forms of energy from a single fuel source. Thermal (heat) and electrical (electricity) energy are usually the two forms of energy produced in many types of cogeneration applications. You can read more about how cogeneration works and the advantages of cogeneration in this article. 

Cummins cogeneration
Cogeneration delivers significantly higher efficiency than traditional grid with central power plants. 

What is trigeneration, also known as combined cooling, heat and power (CCHP)?

Trigeneration is usually the simultaneous production of cooling, heat and electricity through a single fuel source. Some trigeneration applications produce electricity and recover heat while simultaneously utilizing the carbon dioxide (CO2) from the exhaust. This CO2 helps with photosynthesis in greenhouses or carbonation of beverages in bottling facilities.

Let’s now move into the terminology associated with the economic aspects of energy and electricity. 

What is spark spread? 

The spark spread is a metric for estimating the profitability of natural gas-fired electric generators. It is the difference between the price of electricity and the cost of the natural gas needed to produce that electricity 1. As the spark spread increases, savings provided by a cogeneration system also increases.

What is demand response? 

Demand Response is the act of reducing electricity usage during peak demand times to lower your cost of electricity. Generally, customers participate in programs with utilities and agree to reduce demand when needed. To reduce the demand, customers can turn things off, selectively use large loads during off-peak times, or generate their own electricity during peaks.

What is demand charge management?

This is like demand response with a specific focus on reducing demand charges (kW) and associated costs. Demand charge management defines an overall plan which can incorporate several methods of demand reduction and self-generation with the goal of reducing the cost of electricity associated with demand charges (kW).

You can read more about customers' emerging needs around economics, including demand response and demand charge management, making distributed generation an important component of electricity markets in this article.

Let’s wrap by covering the terminology associated with different types of fuels used. 

What are renewable energy sources? 

Energy sources that naturally replenish over time are called renewable energy sources. Solar, wind, tides, hydropower and geothermal heat are some of the examples for renewable energy sources. While the availability of these renewable energy sources could be intermittent, they are considered inexhaustible over time. 

What is diesel fuel? 

Diesel fuel is a liquid fuel obtained through distillation of crude oil. Diesel fuel is a mixture of hydrocarbons, aromatics and paraffins with high chemical energy density. An internal combustion engine fueled with diesel converts this chemical energy to heat and kinetic energy. 

What is natural gas?

Natural gas is a fuel that primarily consists of methane (CH4); it is colorless and odorless in its original form. Natural gas can be combusted very efficiently and emits less pollutants than many fossil fuels. It has surpassed oil and nuclear to become the second most commonly used fuel in electricity generation.
