"The motors had Alnico magnets"
I don't know,, I never had a reason to inspect them. The locos always did what I asked them to do. They were used on a branchline layout where due to terrain and out and back operation the prototype always ran two locos back to back so each only needed to be able to pull 10 or so cars. After changing the wheels sets the only problem I ever recall from the RC geeps was the plastic step treads had a tendency to get knocked off and need to be re-glued.....DaveB
