The Atlas S-2 has some sort of bind in the rear truck or gearbox. We didn't disassemble it yet, but that's where the problem lies.
- HH660 - about 8-9 cars plus caboose.
- L-1 - 10 cars plus caboose.
- RS-3 - 9 cars plus caboose.
- Atlas RS-1 - 17 cars plus caboose! (Maybe more, that's the length of my longest staging track so I stopped there.
Dick insists that the biggest factor on pulling power is weight. I haven't added any weight to any locomotives yet. But I'm optimistic that if one locomotive can pull 17 cars, then I can add weight to others to at least come close. The L-1s and the R-1s need to be able to pull a sizeable train. Of course, starting in 1947 the L-1s are replaced by FA-1/FB-1/FA-1 sets, and all three are powered so those should be just fine.
