Q Did railroads that used Pullman service have their own sleeper and parlor cars too, or were one or the other used exclusively on any particular train? Also, how were contracts structured: Did Pullman pay the railroads for space on the trains and garner all the fares, or did the railroads pay for the service […]

Spotter control
This sign on a SD80MAC means it can move a short distance on battery power through one traction motor. Walter Fertsak Q In Cresson, Pa., this year, I saw a SD80MAC with a little plate above the first axle. What does this signify?— Walter Fertsak, Austria A Spotter Control is a locomotive on-board system used […]

Gantlet vs. gauntlet
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 […]
Railroad air brake systems
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 […]
Air hoses on locomotives
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. […]
Measuring track curvature
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 […]
Ask Trains from December 2010
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 […]
Ask Trains from September 2009
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 […]
Ask Trains from May 2009
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. […]
Lionel diesel horns
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 […]
