This is a self powered passenger car. They were used mostly on branch lines. They replaced a steam powered passenger train. They used a smaller crew, and used less fuel. It was less expensive to run.
There are illustrated instructions included.
The kit has a one piece body. Due to this there is not a lot of parts to install.
This kit is
made with high quality resin, and cast in high quality rubber molds.
This reduces shrinkage. I have put a lot of work into this kit so parts fit
properly, and are as easy to assemble as I could make them. If you want proof read my feedback.
