Another question - will these be a GP7 frame and hood setup with just narrower wheel sets similar to the ES43BBi (and others) developed for meter-gauge railways?
Would there be any clearance issues - either vertical or horizontal - with a standard-gauge frame converted to use on a narrow gauge line?
I know the D&RGW used some boilers from standard gauge steam locomotives for the cores of many of their narrow gauge Mikados.
Thanks in advance for any thoughts!
