Richard Benton (left) with a railroader in a traditional Eastern hat at Potomac Yard in the 1950s. Richardson D. Benton Ben Curtis’ father’s Eastern railroad hat (left) and the new version Kromer Cap will begin offering. Ben Curtis (left) Q My father wore this style train cap in the 1960s, purchased in the Boston area. […]
Q Is it gantlet or gauntlet? My dictionary describes the former as a type of railroad track and the latter as an armored glove. But now my railroad guru tells me that all railroads use “gauntlet” to describe the track. Which is it? – D.G. Townsend, Falls Village, Conn. A Always trust your dictionary. Gantlet […]
Q I just saw the preview for “Unstoppable.” How can a train with no air in the reserve tank and brake cylinders roll away? I thought once all the air is drained the brakes will automatically apply?— Andrew Marino, Lincoln Park, N.J. A Railroad air brake systems need air pressure to function, and it’s held […]
Q This is a follow-up question to one in the July 2010 issue about the three air hoses on locomotives (page 58). I saw engines in the ’70s and earlier with four hoses and some with only two. Why the difference?— Dan Mirabelli, Neenah, Wis. A The two-line m.u. setup was generally for 14EL-equipped units. […]
Q How do railroad design engineers measure track curvature in the United States? I believe it has something to do with measuring the degrees between two radii of a circle having the track as the arc length, but I don’t fully understand how it is measured, or from where exactly on the tracks the radii […]
Q I’ve read that when some railroads sent their steam locomotives in for a complete overhaul, they changed the main drivers to a disc type. Why would they do this?— Alex Jamieson, Chatham, Ont. A Changing to disc-type drivers was done on a case-by-case basis. The older style spoke drivers had a tendency to break […]
Q How do railroads figure how much power is necessary for a train?– Richard Panarese, Mesa, Ariz.A Railroads determine power needed for a train based on the route, and the train’s weight and priority. BNSF, for instance, considers the “horsepower per ton” required based on what officials call the train’s “transportation service plan.” The transportation […]
Q In March Trains, an article on the demise of semaphore signals on the former Monon [Page 14] mentioned that CSX was doing away with lineside pole lines and their maintenance. It said the new system will use Electro Code, a system where signal communications run through the rails. How is this done?– Richard K. […]
Q: I’m having problems with my postwar Lionel diesel horns. One is in a no. 2343 Santa Fe F3 and the other is in a no. 2331 Virginian Train Master. Both locomotives are in like-new condition, and though I know I can buy a replacement horn, I’d like to keep them original and get the […]
Q Can you please explain the visual and mechanical differences among EMD’s SW-1500, MP15DC, and MP15AC switchers?– Andrew J. Jones, Wigan, England A Electro-Motive’s SW1500, MP15, and MP15AC were all 1,500-hp switchers, but the later MP series were significant upgrades to the older SW models. The SW1500, built 1966-1974, used a non-turbocharged 12-cylinder 645E engine. […]
Q I saw an unclear photo of a Pennsylvania steam locomotive identified as an S2, with the number 6200. Two things caught my eye: the 6-8-6 wheel arrangement, and the absence of any visible cylinders or driving rods. What can you tell me about it?– J.H. Lehman, Dayton, Ohio A The 6200 was a one-of-a-kind […]
Q I saw a big tank car (DUPX 29744) at Wilson, N.C. It was quite long, with four trucks. What products do these cars carry? How many are there, how heavy are they, and why so big? – D. Wescott, Wilson, N.C. A It is a 43,800-gallon, 526,000-pound (gross weight) car owned by DuPont, in […]
