Railwelding

Track inspection No. 1: Know thy thermal forces! For John Zuspan, principal at Track Guy Consultants, the most important takeaway for any student in his introductory track inspection course is that rail forces increase with temperature changes. So, knowing that the rail can move (compress or tense), even in moderate temperatures, means knowing that track […]

GP60-series locomotives EMDs GP60 model was the last of a series of four-axle locomotives built with ever-increasing horsepower, designed to lead a railroad’s priority trains. Short, fast intermodal trains were perfect for a GP60s 3,800 horsepower V-16 to send 950 horsepower to each axle. Unfortunately, the double stack era was underway, with longer heavier trains […]

From the Cab: Memories, miles, and money

It always bothered me that I couldn’t identify the engineer in this picture of Amtrak train No. 98, departing Main Street Station in Richmond, Va., on Sept. 14, 1974. He wasn’t the regular throttle jockey, whom I knew. Still, it’s one of my favorite images and was used to promote my first book, From the […]

Santa Fe 3460 Hudsons had an impact on the railroad much larger than their class size would indicate. Mention the Hudson steam locomotive and the name “Santa Fe” likely won’t come up right away. To be sure, the Atchison, Topeka & Santa Fe Railway’s roster was light on 4-6-4s, just 16 of them. And they […]

Stop that train: Railroading is violent business

Worker look under derailed commuter car

Railroading Railroading is violent business. Freight cars coupling sound like small explosions, diesel engines reverberate like distant thunder, and horns at grade crossings are so loud that even deaf people can feel them. So, with all of this violent sound going on, how do you get the attention of a railroader at work? Use more […]

Dynamic braking 101

Wide-field image of an orange locomotive in a barren mountain scene.

The dynamics of dynamic braking A half-century ago, when diesel locomotives were replacing steam engines, a revolutionary breakthrough — dynamic braking — was making freight operations safer and more efficient. Dynamic braking is the method of train braking whereby the kinetic energy of a moving train is used to generate electric current at the locomotive […]
