PRR T-1 Duplex Boiler Mockup

A mockup of a possible boiler design for the PRR T-1 Duplex 4-4-4-4 streamlined steam engine. If it's not obvious, my plan is to build this 8-wide.

 

Looking at the design compared to my #1225, I don't think it'll be that much bigger even though in reality it is, because of the massive size of the T-1 drive wheels. I base the overall size of a MOC locomotive to be proportional to its' drivers, and on these big locos I use the standard large BBB drivers.
