Picked this up last year and I am not sure who made it .Looks to be all brass construction.it has a Pittman type motor that drives the rear wheels only the front are non powered ,I could find no markings or stampings anywhere save for the number 93 stamped on a gear cover.Any ideas on the maker or era in which it was produced?BTW it runs very smoothly even at low voltages. 
Even has an engineer figure! 
i believe poem
Also it will not go around 22 inch curves so it may need 26
Perhaps LMB/Tetsudo?
More light on the engine and less light on the tool board would help…
Good Luck, Ed
Wow ;it sure looks like it!And I didn’t pay anywhere near $572!
Except you said that the front set of drivers was not powered.
True
The geared axle is there but the gearbox removed. A previous owner must have had drive-train issues?
Regards, Ed
Possibly,the gear is there and has signs of wear so perhaps it had a second motor or it may have had a linkage that was removed.
