Great idea. I was thinking about modifying a Walthers Kings Coal trestle, but this sounds better. Besides the Virginian that came with the coal dump I have several of the Tyco Boston & Maine operating hoppers.
I’ve got this old Vollmer coal loader which I bought when I was a teenager.
It has two chutes which are solenoid activated. The building, unfortunately, holds very little coal, but it’s fun to load a car or two.
The coal is dumped elsewhere on the layout:
I built a “volcano” out of scrap foam, painted it black and covered it with WS cinder ballast. The coal drops through the actuator, through the “crater” of the volcano and into a box beneath the layout.
I’ve got 11 of these cars - one C&O, 2 U.S. Navy, 1 Virginian and the rest PRR.
The coupler conversion is a bit of work, but straightforward. I removed the trucks and used a Dremel to cut off the coupler mount, being very careful to not cut into the wheels. The trucks are very solid, and I’ve never succeeded in removing a wheelset, so I just live with the old plastic pizza-cutters.
These cars have nice solid metal frames. I got a bunch of Kadee #5s and some draft gear boxes, plus some 2-56 screws. I drilled and tapped the frame for the screws, and just put them together.
Glad to see other modelers using Tyco operating hoppers. I have 10 Tyco hoppers that I have modified with sprung trucks and body mounted couplers. Tyco hoppers are a near prototype for Southern Pacific ballast cars. This is how I modified my cars. http://lariverrailroads.com/gravel_pit.html
I’m thinking that if i super glue several ball point pen springs together end to end then place them in an open top straw to use as a trough by rotating the springs with a slow speed motor
