Nice @Fatman Mamod has made a very good loco and it was my first live steam engine also... "some" years ago and I still have it. The one i have is a basic model but yours have been greatly improved and must be nice to run. The only problem with those locs is the flanges of the wheels are not very deep and that is a problem to use it on classic tinplate tracks; it also is sometime a speedy model.... and derails easily but that is part of the fun.
