So, my 3 week old Lionel SD60e (Legacy) seems to be running slower than normal. I'm not quite sure why this is. The engine only runs at about half the top speed of my postwar switcher (I'm running an 8 car consist on both engines).
I've checked the track for voltage issues and all is good. I've looked for debris, same, all is good. Additionally, I've cleared the speed limit function on the CAB2 remote so that's not it either. And yes, the engine was lubed (about 3 weeks ago). Is it normal for the more modern engines to have a much lower top speed than their postwar counterparts?
Any input here is greatly appreciated.
