‘RUBY’ #2 Live Steam 0-4-0T

While not a model of any specific prototype, RUBY is a simple locomotive based on Baldwin practice and is typical of small locomotives used on industrial and shortline railroads all over the world. This is an excellent engine for beginners in live steam, as it is simple to operate and reliable in use. On the other hand, it is sophisticated enough to interest those live steamers with more experience.

RUBY 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.
