Hi guys:
Here is an historic photo of a Baldwin locomotive Olomana model type as delivered by the Baldwin locomotive Co. truck !

Chain drive for the truck rear axle.
Gas tank fully exposed at the rear ! Although, at that time the majority of street vehicles were still horse and buggy.
As well, there does not seem to be that much protection for the driver if a mishap occured and the locomotive moved forward from its bed mounting.
Amazing that enough of humanity survived to reproduce!
Read all four pages. Absolutely amazing model building.
