Yes Yes... shipped from Metro East industries to Mid-America Car for a paint job... Before May have been the only stencil they had... or they just plain made a mistake... it's a contract paint shop. 60, 60M, 60B... same guts.
It is interesting that NS is replacing cabs on some of its locos with new cabs, which appear to be very similar to the original EMD cab (SD40-2's). However, on their latest rebuild, SD60E # 6900, it has a very unusal supplied cab.
Besides, I am not surprised that BNSF is adding cabs to these units... B units are somewhat impractical. Unique, but no flexibility.
