Siemens & Cummins partner to build new Tier 4 diesel locos

This article states "109 tonnes":

109 tonnes does translate to approximately 120 short tons of 240,000 pounds.

Well, 109 ton(ne)s seems to have slipped: the data on the press release Fan Railer just linked to says 120 metric tons: 264,000 pounds. Still (as I said a while back) better than recent MPI offerings.

I think the originally released weight was just mis-interpreted by the media sources. Siemens was never specific as to which type of "ton" they were using in the original press release, so it's not that far of a stretch to presume this. After all, 3rd party media is almost always wrong at first when reporting railroad-type news.

Fan railer--
Much as media report every fossil as a "dinosaur," every airplane as a "jet," and every naval vessel larger than a rowboat as a "battleship"! I think you are quite likely right: perhaps (scenario) somebody as Siemens said "120 ton(ne)s" (parenthesized bit not being pronounced, a report thought "This is for a U.S. customer, so that must be American tons," and converted back into metric to get 109.

120 metric tonnes is not a RIDICULOUS weight. It's about what a typical 4-axle freight locomotive of the 1960s would have weighed (GP-40 or the like). Still, for a high-speed passenger unit I'd want to shave the ounces. British Rail managed a 3300 hp locomotive at about 100 tons at the end of the 1950s (the Deltic) and a 2250 hp locomotive at under 70 tons in the 1970s (HST "power car"): surely modern diesel engine technology would allow a passenger locomotive weighing less than 120!

The Cummins-[re]powered Tier 4 freight locomotive for INRD has been completed.

Whats buried in that extended Dynamic Brake blister?,there's no grid vents in the blister.

Good question. Hopefully someone will get a nice roof shot at some point.

Does this have urea after-treatment? If so, maybe it is housed in that area.

Yes.

Here are some much better shots of it. No roof shots yet, though.

First generation diesels tended to have lots of air vents in the carbody. The introduction of the U25B with its centralized air system (I know, Baldwin had central air on road switchers built for North Africa back in the 1940s, but the idea didn't catch on for general application at the time) ended this: The GP-30 and Alco's "Century" series imitated GE on this feature.

So why does it look as if there are a dozen louvred vents along the side, in the engine compartment doors, on this critter?

I guess they felt it was more important to keep their shiny red prime mover cool than to keep it shiny.

Any kind of exhaust treatment will create heat,might be the reason for all the vents,
there will be air filters mounted on the doors on the inside attempting to keep to engine area clean.

Backshophoss--
I would assume so! But then, even first generation units often had filters of one sort or another behind their carbody louvers. Changing the filters every -- well, BN had to change locomotive air filters daily when Mt St Helens erupted; I assume normally the change is at regular intervals somewhat longer than that! -- is a labor intensive operation. Wouldn't a designer TRY to avoid that?

You mean keeping cool is more important than looking cool? (Grin!)
