Q: What are the bars on top of Pennsylvania RR diesel locomotives for? Are they for radio? — Damien Bouchey A: Those aren’t for radio, though they served the same function — communication. Those are Pennsylvania RR Trainphone antennas. In the mid-1930s, the Pennsy was looking for a more efficient way for dispatchers and towermen […]
Q: I have heard of some of the uses for alcohol in model railroading, such as cleaning parts, removing paint, and track cleaning. Are there other uses I’m not aware of? And at what strengths would be used? — Ron Buddemeier A: Isopropyl alcohol is a fairly strong solvent, and as such, there are a […]
Q: I am modeling the Milwaukee Road’s Beer Line in HO scale. Which trains worked the Beer Line, and what were the train numbers they used? I can’t find any information on the internet. They didn’t just call them “Midnight Beer Train” or “Elevator Job,” did they? — Jerry Lane A: The Beer Line is near […]
Q: In your Ask MR question “Is there a way to automatically slow DCC locomotives?” you mentioned Arduino, a DCC-connected programmable system. Is that like Java Model Railroad Interface (JMRI) software, and if so, how do the two compare? — Bruce Fogwell A: Hi, Bruce. Arduino isn’t software — it’s hardware. An Arduino is a tiny computer, […]
Q: I’d like to know how trains turn around at the end of a branch line in the caboose era. I have great affinity for turnaround operations and am designing a new N gauge layout that might feature several of these operations. How do the crews manage to reattach the caboose on the end of […]
Q: I’m considering converting my N scale diesel fleet to DCC. I have a concern about getting realistic sound in N scale locomotives. On videos of model railroads I have watched, the diesel acceleration and running sound seems to feature the high-pitched whine of the diesel generators. When I railfan real diesels around the Pittsburgh […]
Q: What causes a steam locomotive chuff sound? — Tom Huckaby A: Whether you call it a chuff (the railroader’s term), puff, or chugga-chugga, that distinctive sound is made by spent steam and exhaust smoke escaping through the smokestack of a steam locomotive. For a more detailed explanation of what’s going on in a steam […]
Q: I keep seeing references to “team tracks” on track plans. What are team tracks, what are they for, and how can they be incorporated into operations? — Damien Bouchey A: The idea of the team track probably dates back to not long after the invention of the railroad. After all, a team track is […]
Q: My HO scale Broadway Limited Imports Reading Co. T-1 steam locomotive is making clicking noises. The strange popping, cracking noise is most noticeable in curves. Otherwise, the engine runs fine. Although it was bought some time ago, it is operationally new. I’ve attached a short video. Any thoughts? — Bill Franz A: It’s hard […]
Q: I need to calculate the grade on a double deck layout. Though I’ve been interested in model railroading since I was a child, it’s been quite some time since I was active in the hobby. Now that I’m retired, I’m planning a layout. After much deliberation, I’ve settled on a two-level around-the-walls design. My […]
Q: Do you have any suggestions on how to replace trucks on Walthers HO Horizon cars (item No. 932-6073)? — Daniel Kielty A: That part number corresponds to an HO scale Massachusetts Bay Transportation Authority commuter car. The Horizon fleet passenger cars, used by Amtrak as well as municipal transit authorities like MBTA, were built […]
Q: I have a trestle bridge above a deep ravine on my HO scale layout and would like to automatically slow DCC locomotives approaching the bridge to avoid too rapid an entry. Using DCC, is there a method to provide such “auto deceleration?” — Paul Savello, Cedar City, Utah A: Hi, Paul. Such a thing […]
