Does anyone know for certain what the maximum cut-off was for the Big Boys in both forward and reverse (if the figures are different)? I'd assume it would be about the same as Challenger #3985 since they both use the 12" ALCO Type "M" power reverse and had very similiar designs.
I just revisited #4018 in Dallas, but the cab is locked so I couldn't see the reverse quadrant. I asked one of the employees, but he didn't have the keys.
Are any of the reverse quadrants clearly visible on any of the Big Boys that are on display?
Here's a link to my photo series of #4018 in Dallas, TX I took back in March of this year. Just this past weekend I took some more photos and also video taped its whistle being blasted on 100 psi steam. I'll get them posted soon.
