- I can attest to this. I recently wired up an "automatic reversing rig"
- for the club layout. I put in _2_ ohms (somewhat randomly chosen), so
- arranged as to slow the train before reversing (more for appearance
- than anything else. (if anyone made the Boomers Show, in Bedford, NH
- that was it...)
-
- The affect of two ohms was invisible. Obviously, this is dependent
- on the engine. The train in question was Thomas the Tank (or his
- relative, Duck) and two coaches. Drew about 300ma at 8V, if memory
- serves.
-
- (Now later in the day, when we had 5 engines (including pushers) on the
- main, with a 70 odd car train, I'd not have liked to try 2 ohms. 8)>>)
