For the record, I believe this is the first Lego camelback built.
Wow, is this the only Lego Camelback built? Anyway, this is a Consolidation(2-8-0). I was inspired when I saw the Camelback at the Baltimore and Ohio Museum. I used those technic wheels and surprisingly, they work great, but not through switches or cross tracks. I will use that wheel design on my Northern(I credit Christopher Fuller for the flanged-blind-bling-flanged arrangement). NOTE: The prototype for this model was the Lehigh & New England Railroad No. 32.
