Hi all,
I’ve been doing some Extensive research on the F40PH-2C and its compatibility with GE’s GEVO-12 prime mover and if I’m right if the Engine bay is modified to accommodate the GEVO-12 it should be able to run at Tier 4 standards without having to extensively modify the carbody too much (the doors will need modifications to accommodate the GEVO-12.
The F40PH-2C is better than the standard base F40PH because it’s slightly longer and can fit it better. The GEVO-12 Repower will also work with the Standard F40PH-2; it will just need to keep most of the original HEP equipment, or the frame will need to be extended entirely.
MidTrans EMD/GE F40PHAC-4M (The unit has AC Traction and follows Tier 4 standards and has desktop controls, hence the AC-4M)
MidTrans EMD/GE F40PHAC-4CM (The unit ALSO has AC Traction and follows Tier 4 standards and has desktop controls, hence the AC-4M)
What do you think of this? It might be costly, but it may be worth it, or I might consider the 16-710G prime mover, but the frame would need to be reinforced, and mounting points would also need to change, like the GEVO-12, but the 710G3 in the -2C would work better and the 710 and 645 are similar in design.
If weight is an issue, I wonder if the 12 cyl 710 would work - though not sure about meeting Tier 4 standards.
That could work, the frame just needs adjustments and also needs to be reinforced to handle the 16-710G or the GEVO-12
Perhaps bogie_engineer, who did the engine and ‘sled’ design for the DM30 locomotive, can comment on expedient ways to adapt a GEVO-12 to the engine bed area in a F40PH. I can’t help but wonder, though, if that conversion wouldn’t l be better in a P42, with monocoque framing designed around a FDL-16, when there is quite a bit of knowledge in updating other GEs from 16FDL to 12-cylinder Evolution series…
The fun for Tier 4 is where you put all the radiators for the engine and the (I assume) EGR cooling system while staying inside weight and balance. I’d expect you’d be using some kind of split cooling and putting heat exchangers over the engine, which may increase the loading-gage over part or all of the cowl.

EMD basically did this already before the F69ACPH units 450-451 in the 80s as a testbed for AC traction. They had 12 cylinder 710 prime movers in the back with a flush nose.https://images.app.goo.gl/NufTD9HiMPx6PqGTA

I’m aware of the EMD F69PHAC, both examples still exist but are privately owned
