My Atlas/Roco or Atlas/Mehano GP9, GP30, GP40, E7, RSC-2 and SD45 locos all failed by emitting the 'magic smoke' sooner or later. By comparison, a couple of Mehano-made MRC RSD-15s are still running. Several Roco-made FA1s are still running, too. No problems with any of my Arnold-Rapido locos from that same era. Good for you if you have Atlas/Rivarossi FM C-Liners that still run - and run well.
