I recently have been upgrading and completing my MOW equipment. I do have more to do.
They consist of two scratched/bashed wood tool and bunk cars built by Al Small, a GRa gondola I built from a Ted Schneph kit, and a Middle Division MOW X29.
I decided to use K brake systems on these cars, as they represent older equipment and I hadn't built a K system before.
First is the GRA gondola, then it's underbody. The K brake is built from Grandt Line K cylinder and Intermountain brake pieces.
Next is the Bunk car, and its underbody. Al's models are superbly put together, but mine lacked any brake detail. The same Grandt K cylinder, plus white metal brake pieces from my buddy Tom.
All rods & piping is steel wire.
I have the Tool car to add brakes to next.
