Making your cars’ wheels more free-rolling

A “truck tuner” – a double-ended reamer sized for the job – is used to clean and reshape the sockets in an HO scale truck sideframe assembly

Q: The axles stick in the journal boxes of some of my rolling stock. I tried scraping them out and lubricating them.

Recent scratchbuilding efforts prompted me to come up with a simple glue applicator that would put a small amount of adhesive precisely where I wanted it.

Ask MR: Tracking changes in railroad practice

A crossbuck with a stop sign stands at a rural grade crossing with a grain elevator in the distance

Q: I’ve given up counting rivets; now I’m into what I call chronological accuracy. My layout is set in 1956. I’m OK with choosing appropriate vehicles and diesels for that era, and I learned that yellow stop signs were replaced by standardized red signs in the late 1950s, but other questions remain. When were roof walks […]
