I got two and they are beautiful. One is going to go behind a Bachmann 2-6-0 to make it the T&NO mogul it desperately wants to be. (Bach-man - please offer a version with a center mount headlight.) The other will make a Spectrum 2-8-0 become a T&NO engine.
But the best part is the connector cables with female plugs on either end so that you can use it with any Bachmann engine no matter what tender electrical connection configuration come with the engine.
Have these ever been offered separately? It would solve the eternal tender incompatibility problem.
