Now imagine a six axle version of this thing with a 75 to 85 mph top speed. Wouldn't that be perfect for freight service? Electric where it can be (with twice the horsepower!), diesel everywhere else.
Simply start building overhead wires starting with the locations where most tractive or braking effort is needed.
It's exactly what's happening in Europe right now, except that in Europe they only use small diesels, because they're only intended to run on diesel while on yard duty.

Well, you can't have both good diesel loco and good AC loco in one for free. Something should be sacrifice - either electric performance, or diesel one, or a bit of both.

Maybe, but in this case that wouldn't matter:
Considering that the ALP45DP has 3600hp diesel and 4,4 MW(5900hp) electric, you could conclude both it's diesel and electric performance are sub-par for a passenger loco. However, if you were to scale these number by a factor of 6/4, that would give you a 5400hp diesel and 6.6MW (8850hp) electric loco, far superior to a current standard 6 axle US freight locomotive (yes, I know more powerful diesels do exist). Given that it's weight would be similar to a regular diesel freight loco there is no reason a similar tractive effort could not be achievable.

Does a prime mover with that power output (5400 HP) exist today ?

Yes, for instance the one used in the Chinese HXN3 (6300hp), but that may not be able to meet the latest emission standard requirements.
The ALP45DP already has 2 smaller diesels instead of 1. You could enlarge those to 2700hp gensets, but they may not fit in the engine bay side by side any more.
Bombardier has already gone more extreme with the TRAXX DE ME, which has 4 small gensets. 1350 hp diesel engines exist for sure. As your total locomotive may weigh up to 195 tons, weight shouldn't be an issue.

Ah yes, you mean that engine : http://en.wikipedia.org/wiki/EMD_265
A failure, and since then, all diesel locos proposed by GM and EMD are
somewhat 30% less powerful. There is certainly a reason for that...

Weight may be not, but volume ? I know the US loading gauge is quite
generous, but I don't think they want to come back to monsters like the
EE60 or DDA40X...

I'm still convinced it could be done, but I do realise this discussion is purely theoretical anyway. Unless a major overhaul of the regulations happens, I don't see any US freight or even further passenger railroads switching to dual mode locomotives any time soon. As long as the ground taxation rules that differentiate between the built up height (a catenary system is 'high' and therefore taxed extra) do not change, there is just to little track fitted with overhead wires and to little incentive to extend that.

LIRR to get improvements in Brooklyn, part of Barclays deal


By ALFONSO A. CASTILLO March 22, 2015

The $100 million real estate deal that led to the Barclays Center being built over a century-old rail yard is beginning to pay dividends for the Long Island Rail Road and its Brooklyn commuters, officials said.

Seven years into the construction of a state-of-the-art new storage facility to replace the original Vanderbilt Yards, workers will soon punch through a 171-year-old rail tunnel to provide trains, for the first time, a direct path between the yard and Atlantic Terminal.

Amtrak's Oregon service under threat
Tuesday, April 07, 2015



AMTRAK's Cascades service between Portland and Eugene will end if Oregon's state legislature enacts the budget adopted by its Joint Ways and Means Committee last week, which proposes slashing funding for the daily state-backed service on the corridor

The Oregon Department of Transportation (Odot) estimates that it will cost $US 10.4m to continue operation over its next bi-annual funding period which runs from June 30 to June 30 2017, which was negotiated down from the $US 20m requested by Amtrak. Former Oregon governor Mr John Kitzhaber included a $US 10.5m allocation in his budget request before his resignation on February 18 following a misconduct charge

Commuter rail could extend all the way to Haymarket


By Canaan Merchant
April 7, 2015
Greater Greater Washington


Map of the proposed extension and station locations. (Image courtesy of Greater Greater Washington).

“Northern Virginia's commuter rail service, VRE, is taking the first steps to extend its Manassas Line 11 miles farther west, to Haymarket.

The extension would bring commuter rail to three new stations in Prince William County, which is growing quickly. It would split off as a spur from the Manassas Line, with some trains going on to Broad Run on the existing line, and some trains going to Haymarket...”

Don't look like that train has any steps for low level platform. But where is the elevated platform there?

They use high level platforms...
