@GG1 4877 posted:One thing to keep in mind is that the N&W was the last class I to fully dieselize and by the time they did, the cab unit era was mostly a thing of the past. It is really a testament to their mechanical department on how well their steam fleet was maintained.
Yes, the end of the cab units was in full swing when they gave up on steam, but a passenger train pulled by a GP does not have that 'streamline effect' look to it like an E8 or FT gives one.
Thanks for all the comments fellows.
