CSX #4000 has an unusual spartan cab with a flat nose section that’s almost reminiscent of the C&NW’s Crandall cab E8s. My guess is it’s a homemade cab CSX fabricated themselves.
it would appear, based off the comments on the rrpicturearchives site that the nose on the locomotive is the same as the NRE genset locomotive noses, so it might not be a “homeade” job. It at least still looks more or less like a standard EMD cab and nose, albeit with a few changes. Could be worse, could actually BE a Crandall Cab…
The new nose and nose found on CSX #4000 was not fabricated by CSX nor designed by CSX, it was acquired via third party vendor. All of the SD40-3 rebuilds will feature this design.
Well that is certainly different. What other changes did NS make to the 6900 to make it an SD60E, just as I’m curious to know what CSX did to make 4000 a SD40-3, I’m sure that there was an electronics upgrade in both, but I’m curious as to if anyone knows specifics.
Besides the obvious (The new widecab to replace the damaged Spartan cab), it’s been upgraded to Tier 0 standards.and has a EM2000 microprocessor control system with an all new electrical cabinet. The prime mover is now a 710G3B-EC . The locomotive has been changed to short hood forward operation. KNORR (CCB2) electronic air brake and motor-driven air compressor installed along with “Layover equipment” and split cooling installed.
Got some of that information from a web forum, and confirmed those details and got several additional details from the AltoonaWorks website.
IINM, The SD40-2s CSX is rebuilding to Dash 3 specs are getting completely remanufactured prime movers and alternators as well as a Q-Tron Microprocessor control system.
I would imagine the corners of the nose have a big piece of steel that is ment to help with crashworthyness. The original nose being nothing but sheet metal.
Still higher costs to install common rail fuel injection system. Plus you would have EMD as the only possible parts supplier for parts that close to current production. Parts for EC engines are available on the remanufactured market.
And thinking about it, NS doesn’t have to deal with any Fleet wide Emissions agreements with CARB the way UP and BNSF do, so the cost may not be worth it.
