Just my opinion but I highly doubt they will use a speed reducing gearbox to allow for the medium speed alternator.
According to the news piece: "Cummins officials said Toronto's GO Transit is the first QSK95 customer in North America. It will repower 11 locomotives with the motor in 2014." The oldest MP40s will be six years old in 2014. Someone really wants to remove the tried-and-true EMD 710 plant for a high-speed diesel? Have they really thought this through?

This is were CAT and the Other OTR compaines are going to have a HUGE advantage breaking into the RR side. Why you are going to ask Tier 4 is what we have been at for 3 Years already we know WTH works have had 4 years of Testing to GET IT TO WORK and also have the Mechanics trained as to what can and will go wrong at the Dealerships so tech support WILL BE READY.
BTW anyone that works in the roundhouse or shops have FUN with ULSD when it hits the RR's that stuff will make you almost wish for the days of a 567 A block with a Water jacket leak into the Oil pan. Trucking company around here went thru 52 Injectors on there 10 2003 KW's with CAT C-13's before they got them sorted out. Were seizing up faster than ALCOs Smoke.
It's a 4 stroke high speed. I had not heard it was Tier 4. In fact the press release says its "ready to meet" tier 4 and it will use SCR. Not that it does these things now.
Speculation on Loconotes is that the ALCX SD90s are going to get this engine.
I still want to know what alternator is going to be mated with these. Are they going to step down to mount an AR10?
Everything Cummins makes is 4 stroke.
Are these two-cycle or four-cycle?
