Most model railroaders fail to create a transition from incline to level track. It does not require much to sand down the 'point' of top of the incline with the level adjoining roadbed. Problems multiply with a curved adjoining section because the wheels may not 'find' the right spot to land... usually resulting in a derailment. BTW... the steeper the incline... the longer the transition will be necessary.
Well, rats! Looks like my ancient but reliable MRC 2400 finally died on me. Gonna take some locomotives that are giving me headaches to my Hobby Shop to test them on flat track and hopefully they behave. Guess I will look at what power packs he has in stock....[wanders off muttering...]
Could it just be the reversing switch? I've had them fail on a couple of MRC's over the years. It was a fairly straightforward replacement once I got the case open.
Switch seems to be okay, the unit seems to have just gotten too cold, so I am going to work up a quick and easy disconnect to be able to bring the pack inside. To quote a great 20th Century philosopher..."You're dethpicable!"
