The decline of North America’s hump yards

Tilford

Hump yards The number of hump yards operating in North America has dropped precipitously over the decades. Today there are 36 active hump yards operated by the big six Class I systems and terminal and switching railroads. That’s down from 59 in 2002, 72 in 1993, 122 in 1985, and 152 in 1975. Yet hump […]

“F” stands for Front

If you look closely at a diesel locomotive, you’ll see the letter “F” stenciled near the stairs. As obvious as it seems, the “F” stands for Front, and it’s required under the Railroad Locomotive Safety Standards section of the Code of Federal Regulations (CFR). Title 49 CFR Part 229.11 reads, “The letter “F” shall be […]

Deciphering railroad lingo

A worker holds a pole next to a steam locomotive moving slowly.

Railroad lingo What is the railroad’s lingo? Utilized mostly by railroaders, it’s a way of speaking among co-workers that involves using railroad terminology, jargon, slang, or argot. Common lingo can vary from one group of individuals to another. Not born of this world, I’ve struggled to understand some of the language the railroad professionals use […]

Drones With artificial intelligence growing at breakneck speed, businesses worldwide are experimenting with drone technology. No longer just a topic for science fiction, the use of drones has expanded rapidly over the last decade in a wide range of industries, including railroading. In the 2010s, Class I railroads gradually embraced the use of drones within […]

Behind the blue sign

Commuter train passes crossing gate

Look closely anywhere a road or pedestrian walkway crosses railroad tracks in the U.S. and you’ll see a small rectangular blue and white sign attached to the nearest warning device. Officially dubbed an Emergency Notification System, or ENS, sign, it has two vital pieces of information: a U.S. Department of Transportation “National Inventory Number” unique […]

Amazon’s rail operations: Intermodal’s uncommon carrier

Truck trailers ride on railroad flatcars

Amazon, the Internet shopping giant, is also intermodal’s uncommon carrier. To understand what makes it different, a brief overview of railroad intermodal operations is in order. In the early days of large-scale U.S. railroad intermodal operations, described more accurately at that time as “Piggyback”, or TOFC (Trailer On Flat Car), the identification of these vehicles […]

Digital Train Inspection: Artificial intelligence boosts safety

A train passes through a tall, gray, open-ended shed

Norfolk Southern is installing Digital Train Inspection (DTI) portals at key locations on its 22-state network. Each portal features sensors, stadium lighting, and an array of ultra-high-resolution cameras mounted above, below, and on either side of the rails. As trains pass through the portal — at speeds up to 70 mph — images from the […]

Microprocessor control: Computers in the electrical cabinet

Microprocessor control New locomotives have largely included some sort of microprocessor control since the 1980s when EMD’s 60-series line and GE’s Dash 8 line were introduced. These advanced systems expanded the ability of new power to basically haul more and break down less than older designs. But the thousands of locomotives built prior to this […]

Trackage rights: Same line, two railroads

Three red and yellow diesel locomotives exit a tunnel and round a curve in hilly country

Trackage rights are one of the main reasons you may see a train from one company operating on tracks belonging to another company. Geography, for example, played a role in the long-standing agreement governing Union Pacific’s crossing of California’s Tehachapi Mountains. When this line was built by the then-Southern Pacific, there was no room for […]

Train handling is a science

Three orange and black locomotives curve round a green hill

Train handling The United States Bureau of Labor Statistics estimates there are more than 36,000 locomotive engineers in the United States. Whether it’s an older Geep switching cars in an industry, a passenger train racing across the country, or a Class I freight on the main line, the techniques that engineers learn and have at […]

What’s behind today’s intermodal equipment

Two red and light locomotive leading train of containers

Intermodal equipment If you’re trackside, odds are you’re going to see an intermodal train. Intermodal made up 49% of the 34 million units of freight carried by U.S. railroads last year, more than four times higher than coal, the next largest commodity. Odds are that intermodal train will mostly have railcars owned by TTX, a […]
