Only Amtrak and state of California have P8-32bwh's they were built in 1991 as Amtrak 500 thru 519, 501 and 502 became CallDOT 2051-2052 They were built as a stop gap measure when Amtrak was short power and the Genesis was still in development.
At 3200 hp they are good for short to medium size trains, the HEP is tapped off the main alternator, the engine runs at 900 rpm when in hEP mode.

Thanks Dutch...
So the prime mover is at a constant 900? It's almost like a next generation U34. Im assuming GE no longer builds new units, favoring the Genesis. How do you feel about the Genesis Dutch, or anyone else who operates them? I wonder if NJ Transit gave that model any consideration before going to Altsom. I'm not an engineer so I have no clue, but I have heard EMD engines are better for commuter service because the RPM can increase much faster then a 4-cycle GE. Any comments?

My views on Genesis and PL42ac are pretty much discussed on MNCR and NJT board, I won't repeat the info here. but the P32acdm does very well in commuter service

GE's latest passenger locomotives -- basically from the P32-8BWH on up to the P42DC -- were really designed more for corridor and long-distance service than for the constant start-and-stop of commuter service. That doesn't mean they can't perform well in commuter service, but it's not exactly their forte.
As the new EPA environmental regulations come into play, I think you will find that EMD locomotives won't accelerate that much faster than GE locomotives. In fact, I've heard that GE's latest freight locos with the new GEVO engine actually load/accelerate a bit faster than EMD's newest units, which still use the venerable 2-cycle design, albeit with substantial modifications to meet environmental regulations.

The MP36 has a 16-645F rather than a 12-710G (as used on the F59); I'm not sure if that makes a difference, but it's worth mentioning.

Thanks for the reply's guys.
About the Caltrain MP36, I remember reading somewhere that since the units were built and delivered before the Tier II emissions regulations were mandated, they just had to comply with the Tier I. I'm not sure about Metra's units, I think they might be newer. MEC407, thats a good point that EMD's may not be so much faster with the new regulations. Im waiting to see how the PL42AC's accelerate, I'm not sure whether it has the 710 or the 645.

I'm pretty sure the PL42AC has a 16-710G, which would make it more powerful (and theoretically faster accelerating) than the F59PHI and the MP36.

Over at Metra the MP's do NOT smoke like the F40's. The older batches of F40's here can make an RS11 proud some days. The MP's just 'splode. Or so I hear, I have no bias against them - I actually like them because they are easier to photograph (don't ask me why, the pics just turn out better)

The P32ACDM has the 12 cylinder engine. I am not familiar with there being a PL42ACDM???
The P32ACDM is essentially a p32-8.

The P32ACDM is essentially a p32-8.
and GE has a P42ACDM on books but with 12 Cyl GEVO engine.
No not at, all comparing the AC powered and all inverter drive of a P32acdm to the DC variant of the P32-8 is like apoples and oranges.
yes the both have the FDL12 as prime mover, that and the headlight bulb and comparison stops.
The P32-8 has conventional airbrakes.
The P32ACDM has EPIC brakes.
