UP SD70 posted:I actually have a 100 Watt Z500 that I've been using on my Fastrack oval. I think 100 Watts should get me started on this inner loop. I just will need to have some power drops along the track so it doesn't lose speed or stop at the other end.
If you have good track joints, you may not any need drops. Only add them if you get some voltage drops or a train slows down. The Z-500 is a little weak, but you have it, so try it out. it's 48.5 feet of track.
