I have a remembrance of a wreak rebuilt by a pool road in a custom config.
It would be good to find a resource for N&W power in it's original config specs...
I saw a former N&W GP30 in the 500 series that I could swear had a wide window on the cab, side facing long hood, right side.
The carbody would of course have a space between the air duct & the cab. I can't find forever a pic, I don't dream such things....
It was not an extended GP30 cab.
I don't know if it had dual controllers but it would be a good candidate...it had a "high-short hood"(EMD local 'cousin licence supercedes "foamer" status).
