I received a Bachmann GE 44 tonner new in box of EBay cheep. Upon receiving it I was disappointed at just how light the little engine is. On my flat loop I have an issue loosing traction on 18 degree turns pulling 4 Athern box cars. The cars are on the light side IMHO since they have no additional weight added. I had wanted to use this for a MOW train but it cannot pull more than four cars, there are currently five with two more being built for the MOW.
