No, I mean the Canadian Safety Cab which specs were developed by CN and introduced in 1973 on MLW M420s and EMDD GP38-2Ws.
You are trying to lump apples with oranges. The Canadian Safety Cab has a very stringent set of specifications including minimum thickness of the steel plating used, no window allowed in the nose door and a strict maximium size of any glass pane in the cab. All Canadian Safety Cabs have 4 front windows whether they wre built by MLW/BBD, EMDD or GE. The specs were developed by CN and there is no longer any locos being built to these specs. The last units to be manufactured with the Canadian Safety Cab was CN's first order of dash-9s.
Is what we are distilling from this safety cab debate that there are 2 distinct designs of the safety cab?
Not even that's true, because even when looking only a units built for the U.S, there are different standards that the cabs were built to.
Don't get me wrong, but when it comes to wide-nose cabs, my give-a-rip meter is broken as to what they're called. Anymore, finding new locomotives with standard noses is akin to finding a needle in a haystack. North Amercian, Canadian, who cares? It's all wide-nose cabs to me, and EMD and GE have their own variations. If it originated in Canada, fine. Lessee.......we WERE discussing the possible disappearance of GP60Ms from the BNSF roster at one point, weren't we?
