Emission control and waste management among top priorities for railroad industry today
On February 28, 1827, the Baltimore & Ohio Railroad became the first
U.S. railway chartered for commercial transport of passengers and freight.
Key facts about the first U.S. railway include:
- The Tom Thumb steam engine was designed by Peter Cooper
- The first railroad track was only 13 miles long
- Charles Carroll, the last surviving signer of the Declaration of Independence, laid the first stone when
construction on the track began

Fast-forward 188 years.
Here is a snapshot of what the railroad industry looks like today:
- 140,000 miles of railroad track
- 21 regional and 510 local railroads
- 221,000 jobs
- The rail network accounts for approximately 40 percent of U.S. freight moved by ton-miles (the length
freight travels).

While railroads have operated successfully for nearly two centuries, the priorities of the railroad industry
today look very different than those of 1827. Today, environmental priorities are top-of-mind for railroad
companies today. Pressure from government regulations, including emission control and better waste
management are ongoing and getting stricter.
But, even more than that, today’s railroad companies are driven to go beyond the basic regulation and
compliance requirements. One example, CSX’s Trees for Tracks
program has planted 23,000 trees since the program began. Similarly, Norfolk Southern has completed 65
percent of its Trees and Trains project, a $5.6 million initiative to reforest 10,000 acres with more than 6 million native
hardwoods and cottonwoods in the Mississippi delta.
Emission control
Designed to decrease fuel emissions and increase fuel economy, the EPA finalized a 3-part program that will
dramatically reduce emissions from diesel locomotives of all types: line-haul, switch, and passenger rail.
The standards are based on the application of high-efficiency catalytic after treatment technology for
freshly manufactured engines built in 2015 and later.
Locomotive manufactures are doing more than just meeting minimum requirements, though. Locomotive
manufacturer Union Pacific’s Genset
locomotive features smaller diesel engines and generators instead of one large engine. When compared
to traditional diesel locomotives, Gensets reduce gas emissions by up to 37 percent and emissions of oxides
of nitrogen by 90 percent.
Union Pacific isn’t alone in their pursuit for solutions that meet and exceed emission control
standards—other manufacturers are also focused on improving technology designed to power trains.
Waste management
Recycling is a key waste management initiative for locomotive manufacturers and railroad yards. In the last
three years, CSX has recycled 8.52 million crossties and currently reuses or recycles 95 percent of its
crossties with a goal of increasing the rate to 99 percent by 2015. Additionally, Kansas Southern Railway
transports used locomotive lubricating oils to a refinery for reclamation and recycles used locomotive and
signal batteries, among other recycling initiatives.
Minimizing and managing fuel spills are also top priorities for railways and railroad yards. Typical U.S.
railroad yards serve hundreds of locomotives a day, filling each with up to 5,000 gallons of diesel fuel at
a time. At most yards, spilled fuel, process run-off water and used oil collect in a catch basin and mix
with rainwater and runoff, which can also contain oil waste.
The petroleum must be removed to ensure the wastewater is suitable for discharge into a public sewer system.
One way to remove petroleum from the wastewater is via an oil skimmer. Removing as much oil as possible is
important to railroad yard management because—in addition to protecting the environment—it keeps other water
treatment equipment, such as filtration systems and oil/water separators running smoothly and efficiently.
What will the future look like for the railroad industry? While no one can know for sure, emission control
and waste management will likely be top priorities for years to come.

practice?
