‘IDA’ Ruby #3 Live Steam 0-4-0ST

This model is now discontinued.

Based on Ruby design, Ida will easily lend itself to kitbashing and cosmetic modification. The sheet-metal work (cab and tanks) are designed to be easily removed, leaving a complete running chassis and boiler ready for a new superstructure. With a little imagination and ingenuity, the tanks can be eliminated and a tender added, leading or trailing wheels added, or other changes can be made, resulting in your own unique locomotive.
