Fixing N scale coupler problems

A hand uses a red plastic pick to uncouple two N scale freight cars

Q: I’ve tried many methods to uncouple my rolling stock automatically rather than use a manual tool. Permanent magnets were far from satisfactory even when I devised a way to raise them at the appropriate time to a position closer to the couplers. I’ve modified an HOn3 electromagnet to fit between the rails, and this […]

How would small feed dealers receive grain?

An orange, wood-sided feed mill with attached grain bins is seen on an HO scale train layout

Q: I have acquired a vintage Suydam “Purina Chows” feed mill kit. What would be contained in the silo part of the building (grain or feed) and how did those feed dealers receive grain? Dumping grain from a boxcar seems a bit messy, and covered hoppers were not in use until the mid-1950s. I model the […]
