SCRRD anounced order for 20 new F-125 EMD 4700 HP for MetroLink. AC traction with HEP. Other details lacking. Here is Railway age link.Max speed 125 MPH.
every one is going for the 125 MPH loco speeds
Intersting that it is 4-stroke cycle and not 2-stroke. EMD under Hamilton, as an independent, was planning 2-stroke compatibility with Tier-4 without much after-treatment of exhaust. Aparently, that effort has been abandoned in favor of using Cat’s technology.
I would like to see how EMD’s bid stacked up against those from MPI and Brookville, assuming they decided to go after the Metrolink order. It will also be interesting to see if EMD will go after any other suburban locomotive business in the future.
Not cheap!

At least $6M a pop!
More than double what a six axle freight locomotive costs. Ouch!
I’ve read some speculation that the Cat high speed 4 cycle engine is lighter than an equivalent 710 and that may be the major reason for it’s application.
Cat/Progress/EMD is still planning to offer a Tier IV SD70ACe with the 16-710 so that engine line stays in the catalog, at least for the near future…
It may be because Metro link specified 125 MPH capable and that almost requires AC traction motors. I do not believe MPI & Brookville has any 4700 HP AC loco ? In fact do they catalogue any AC traction ? ? That speed also requires not having nose hung traction motors. Do these other manufacturers have that ? ?
So, Blue, are you saying GE was the only competition?
Unknown if even GE has a 125 MPH AC traction, non nose hung traction motor loco even in development. Now European builders ? They may have the technology but crash worthiness ? The 4700 HP is puzzling as that may be a phantom number.
Is that prime mover HP, Max traction HP, Max traction HP with full HEP in useage, low minimum speed for full HP, & other performance figures?. Anyone know brake HP of this prime mover ?
Yikes, that thing is weird-lookin’! Would it be so hard for EMD to give it a “Bulldog” nose?
From http://www.railwayage.com/index.php/mechanical/locomotives/emd-reenters-passenger-rail-market-with-spirit.html - “The F125 Spirit consists of a streamlined Vossloh Rail Vehicles (VRV)-designed monocoque carbody with one control cab equipped with CEM (Crash Energy Management); a turbocharged, 20-cyclinder; four-stroke Cat® C-175 20 diesel engine; an AC traction propulsion system; VRV high-speed trucks; inverter-controlled HEP (head end power), “and all the accessories necessary for single- and multiple-unit operation suitable for commuter and intercity service.”
So it’s basically an uprated, Americanised version of this - http://www.vossloh-espana.com/en/products/diesel-electric_locomotives/eurolight/eurolight.html ?
(the datasheet for the ‘slimline’ UK version is here - http://www.vossloh-innotrans.com/media/downloads/pdfs/vrv/Vossloh_UKLIGHT_us.pdf - 15 of these are on order for one of the UK operators)
One thing I find interesting is the use of SCR(catalytic converter) engine. I can not say about that large of an engine. However in trucks most companies are going with DEF. SCR engines tend to be real fuel hogs. 15-20 percent loss in fuel economy. Rgds IGN
From the beginning of the tread, all this Metrolink ‘new’ EMD looked like a ‘conversion’ of Vossloh’s design. It’s now been some time since EMD and Vossloh have been cooperating in terms of locomotive business. However, most engines sold (I’m talking about the previous model, the Euro 4000) have been for freight use, although the Euro 4000 also has a passenger version in catalouge, that has only been sold to Israeli railways. The Eurolight is just an euro 4000, V2.0. So all the process of creating a ‘new’ pasenger locomotive design by EMD is not so new,
The Vosslov loco sold to Israel Ry has an EMD prime mover
Indeed. Israeli units are Euro 4000s, the only ones built for passenger services, having a top speed of 160 Kmhr, or 99,5 Mph. Here’s a video

It seems more like Progress Rail is buying a Vossoh kit and having EMD assemble it then slap “EMD” on the side.
Some more info about EMDs newest passenger locomotive. Let us start with the heritage, i.e; the Euro 3000 and 4000.

There’s even a ‘dualie’ prototype :

Don’t know about anyone else, but I think that this new F125 is not so ‘new’ since it’s the result of developments abroad, especially in spain, wher the Series 334 has been in use for several years now. Yet, over there, the lines in wich such units work have only short sections of 125 Mph capable sections, with the notable exception being a small period in wich these locos were allowed to ‘stretch their legs’ in the Galicia HSL, during a short period just after the opening of that line, when the electrification was still being completed. Anyway, I’ve rode train behind such units and they’re a little slow accelerating out of speed restrictions.
And here’s the ‘official literature’ from EMD : http://www.emdiesels.com/emdweb/products/pdf/2-sidersENG_LTR_proof_rev5RevE.pdf
A little slow accelerating out of speed restrictions? What length trains and what horsepower?
It can be safely assumed that Metrolink is going to have little to no need for the 125 MPH capabilities of this locomotive. So why did they go to EMD instead of re-ordering with MPI, which has a proven suburban design?
Normally Talgos, wich tend to have something between 8 and 12 cars, wich is something in the vicinity of 200 metric tons. But it’s only noticeable when coming out of speed restrictions. Acceleranting from a standstill they’re fast enough
