Morning!
I’m kinda on a sugar rush, I don’t know LOL 
But I’m curious to know, if you could bring back one discontinued/outdated Locomotive model for modern mainline service - updated with today’s technology - what would it be and why?
I’m just curious because it’s getting to the point where the unimaginable is sort of happening 
For me, it would be the GG1 since it’s a more iconic locomotive and it’s also a really nice looking one in the PRR pinstripe paint

Ohh…
If you count reproducing a locomotive that is now all gone (the GN’s W-1 electric), then it’s the W-1.
Here’s the MTH website because it includes some neat history thereof: Great Northern O Scale Premier Cascade W-1 Electric Engine With Proto-Soundr 2.0 | MTH Trains.
The revised Ingalls Shipbuilding 17-A passenger unit, perhaps with a QSK95 to replace the Superior 75-LX-8 LDS-2500.
In 1946 the 17-A (then diesel-electric) was suspiciously similar to the Baldwin Gravel Gerties – short overall length, large cylinder displacement slow-speed engines, A-1-A trucks. However, the use of the Bowes tugboat drive for the revived PRR V1 turbine circa 1947 was brought up as an alternative to individual traction motors, preserving the cost and speed advantages of mechanical final drive.
The GG1 or any other electric locomotive would be a no-go because you don’t have the catenary or other infrastructure to run them.
Well i think we all know that this is just interest based to see what should come back or should have basically 
Zug, what are the former CEFX AC44CWs classified as with NS since they were factory built AC44CWs and NOT Dash-9s?
I would love to see a modernized SD45X come back to the rails. That locomotive was ahead of its time and would have fit in well with today’s rosters.
That’s true, it was ahead of its time.
You’d have to check the blue card. I’ve never had one so I don’t know.
EMD E units, ALCO PA’s, or even Baldwin BP20’s to replace the ugly Amtrak locomotives.

Great Northern Baby!!!
They kept the orange, but the original colour scheme looked better!
Too many edits

BNSF really needs to up their game with heritage units 
Its disappointing for their ‘Heritage units’ they need to b decked out in a special paint to be heritage units in my opinion
Agreed. Crowding a bunch of logos onto one loco hardly counts as a heritage livery. Of course with Santa Fe locos still all over the BNSF network we get to see some real heritage units all the time!
General Motor’s Aerotrain. With modern welded rail, vastly improved suspension, and a better diesel engine (with more power!) at the head end it could work nicely.
If you want to keep diesel power, Cripe’s ‘DMT’ (the follow-on to the TurboTrain) would be a much likelier solution than the GM attempt with lightweight bus bodies. My opinion is that both powered negative-cant-deficiency effectiveness and good magnetorheological damping solve the Turbo-style ride concerns (if not the transmitted axle noise) whereas you’d need active suspension and at least three-axis damping to debounce the Aerotrain. I have looked many years for an engineering analysis for what GM put on the ‘tenth car’ that supposedly solved the ride problem… but my guess is that it really didn’t.
I think there is a future for lightweight (as opposed to HSR) trains… but not cheap lightweight trains.
The F40PH in Amtrak Phase 2 striping. The modern safety cab and dynamic braking would blend well with that paint job but I don’t know if you would want to keep the engine compartment as-was or convert to a modern hood.
I would bring back Sante Fe No. 3416 due to the fact one is in my home town. And that they are a beauty when they thunder down the mainline.
Bring back extinct? Bring back existing/stuffed-mounted in a museum/park? Bring back planned but not built? For the last hypothetical I’d like to see the Lima 2-8-6 with the double belpaire firebox in the flesh.
