Heres the Modified 3927 with a Lionel 2028-100 installed pushing the cars ...
First item I made it with traction tires and it starts out slow no slipping and plenty of power and speed or slow
speed.. ,... AS a side note I DON'T know why Lionel never did this the field is the same Size as a 200 serie, 600 series and most motorized units EXCEPT taller and with its own contain bearings for the armature and all the motorized units! I know they could of done it .. they had the parts and where still using them in the GP and F3's of that time period.. and nobody would of ever called them... cheap or ever called them junk compared to the 1950 units ,
The parts I used are from all the same time period.. Gee I wonder if I could put a 2028-100 in a handcar (lol)..daniel
