pferddy posted:GRJ and others -- Could you describe how and what you do to power the engine while it is upside down in the locomotive cradle? I am a novice and have not powered a locomotive except on the track. Also to repeat what Ponz said -- isn't the Dremel wire brush abrasive? Thank you.
By the way GRJ, your layout build is amazing.
You can power the engine with a couple of leads from the transformer - which I do. I go through a ton of Q-tips & alcohol.
