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, 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 […]
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 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 […]
DC-to-AC rebuild During the middle of May, Canadian National tested its first modified DC-to-AC rebuild on an ore train in northern Minnesota. This is the first step to replacing a fleet of older General Electric locomotives that were built over three decades ago and currently handle the majority of the region’s ore. Canadian National’s Minnesota […]
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 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 […]
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 […]
From short lines to Class I railroads, you’ll likely come across a mainline steam excursion with one or more tenders/tank cars coupled right behind the locomotive’s main tender. Water is the primary commodity, all for the steam locomotive when out on the road. The use of an auxiliary water car, sometimes referred to as a […]
From short lines to the Class I railroads, chances are you’ll come across a mainline steam excursion with one or more non-passenger railcars near the front of the train (sometimes coupled directly behind the locomotive). They’re carrying, as the name implies, tools and more to support the steam locomotive when out on the road and […]
Types of dynamic brakes Dynamic brakes are a supplemental braking system that is the conversion of a locomotive’s traction motors from electric motors to electric generators. This allows a train’s speed to be adjusted by the engineer using a lever in the cab to vary the amount of electricity sent through a series of resistance […]
“Diesel Helpers” are two buzzwords associated with today’s mainline steam excursions – from short lines to Class I railroads, and even selected tourist railroads off the national network. The use of one, or lack thereof, differs between railroads, organizations, and their operating preferences. Some are comfortable letting the steam locomotive travel solo. Others would prefer […]
