Arutha:
I forgot to mention that this is taking place before I ever got around to putting in the balance wheel assembly. The Elgin has a small pallet fork “bridge” (I know that’s not the correct term – someone please give me the correct name for it) that holds it in place allowing one to move the train without it flying apart before the entire thing is assembled, so I haven’t had to deal with that issue – yet. 
Thanks!
Tom
