Greenway (http://www.greenwayproducts.com/a_drivers.shtml) has 82" box pok drivers, which are pretty close to the 84" on the prototype.

I think that you could bash one on a Bowser T1 chassis.

Personally that would be about the last choice I would do as a lifelong PRR modeler but to each his own. You should start by doing some internet research as several people have dimensional drawings on web sites. Try Gary Mitners web site. The reason I wouldn't build that one is it had a huge wheelbase that you are either going to need huge curves (maybe 72" radius in HO) or figure a way to articulate it like Rivarossi engines. Once you overcome that you have the problem that there was only one and it only ran a short time between Chicago and Crestline in Ohio. You might want to contact MTH and ask them where they got the drawings to make it. I am pretty sure the PRRT&HS would have drawings in their files but there is going to be a cost to get them. Nearly everything about it is going to need to be scratch built including the drivers.

Has anybody scratchbuilt Pennsy's 6-4-4-6 S1? I wi***o do so myself, but I cannot find much about the dimentions. If anybody has anything, it would be helpful.
