Transformer Output
Marvin has a question for anyone with knowledge of transformer output:
“I put up an elevated train in a room, approximately 12 by 15 (54 feet of track). The O train runs very fast by the station where the transformer is connected, but slows down as it gets to the other side of the room. I have a K-Line hobby transformer. It produces 0-20 volts AC. Is it too small to run a train on a track of this length? Or is there something else I can do?”

The problem doesn’t lie with the power pack, but with the track. Regardless of scale, track is a poor conductor of electricity. The solution is to run a track buss under your layout and connect track feeders from the buss to the track approximately every 3 feet. Copper wire is a much better conductor of electricity.
You’ll find that the train will maintain an even speed around your layout.
You can also improve the situation by soldering the fishplates (if appropriate for the type of track), but Ken’s comment is the best answer, Just make sure the track buss is adequate cross section for the current drawn by the loco.
