Thanks for the information. I just already request a smoke unit for this locomotive. I saw the diagram of the locomotive and compare iwith the  model of Bachmann Trains Usra 0-6-0  4432  and the conclusion is the same machine, but the difference is doesn't came with the smoke unit.

Hello i have a doubt about these steam locomotive 0-6-0

if these locomotive has include the smoke unit generator?

Thanks you

The best regards

Alejandro
