Great build Frenchie... but you gotta get rid of those road wheels... kids have to be taught to keep on track at an early age.
If I may suggest, a close up happy snap and/or maybe some further detail on that not so tender coal stack could help other train builders... after all the kids want the train and not lumps of coal from Santa.
If your first cut is too short... Take the second cut from the longer end... LBD
