When the Seneca was rebuilt in 1862, she got Stephenson valve gear, which required the removal of the 2nd pair of drivers. Later rebuilt Pennsy camels lost their boiler-top cabs and got more conventional houses on the back end. Also, they lost the Winans firebox, replaced with better designs.
Yeah, i'd desaturate that a wee bit Frank! Was this the right color?
Hey, love the left-handed headlight on the B&O 170. Seems weird but so were the camels. Are you going to make that cab-forward camel too, Frank?
I did a "proof of concept" working with the more modern version of the "cab forward" camel CENTIPEDE.

It was pretty simple I just moved things forward and extended the piston rod and crosshead guide. From the drawing it looks like Winans did the same thing. The animation still works, I didn't mess with the running gear, didn't have to. I'll give the older version a shot.
Still working on SENECA. Trying to get the valve gear to work. The eccentrics are given me problems. I think I'll skip the whole parent/child thing and animate part individually.
