When I returned home from work yesterday, my 4 year old grandchildren, (God love them?) had derailed by HO train on my wife's Christmas Village layout. My wife warned me not to try to run the train as it was derailed. Well, after putting the little HO Bachman Southern 0-6-0 back on the tracks it wouldn't move/budge/go/forward/backward, not even after a little nudge--which sometimes helps. I disassembled the engine on my basement work bench and inspected everything. Everything seemed okay; no broken or miss-aligned pieces. I thought maybe it had fallen off the table. So I did the WD 40 trick as it seemed the wheels/motor wouldn't turn. I reassembled the engine and tried it on the track again. Wallah ! It worked----but it was like the Fourth of July---you can see sparks flying where the engine wheels meet the track and it squeaks around some curved track. My daughter suggested oiling the engine joints and letting it sit on a paper towel overnight so the excess oil can drain on the paper towel and not on the track. Tell me. What are you thinking ! :cry:
