I've been playing around with whats been constructed so far with my fleet of steamers. It seems the ones that got regular use on my old layout are not working so well anymore... My Athearn Challenger is stalling out quite a bit and requires a lil tap to get going. I've tried cleaning the wheels but it's still stalling out... even when it's right over the feeder tracks. Curious what could be going wrong there. My Walthers 0-8-0 switcher has always given me problems and might get retired to ebay sans' decoder if things don't improve. It just stalls out no matter where it is. I pretty much gotta push down her for it get power. I think she needs more weight... anyone got any sites with mods for this loco? Other than that my locos' seem to be working great. My Kato mikado is having issues but I know whats wrong there (melt the brushes by accident when installing the decoder).
