Short lines? Or do they get plenty of castoffs from Class I’s or leased units?

Excursion?
Next stop, Willoughby

The lack of demand from shortlines for B32's helps explain why UP donated a couple to museums (both Pomona and IRM got fully operational units, and I believe there was a third given somewhere).

MTUA: The LIRR could be a possibility for the 700 series dual mode units as a good example.
With only 20 operating DM30 locomotives requiring two each on any through Penn Station
trains they could find a good use there.

They could also put to use some of those PTC equipped units to run alongside their now 20 year
old DE/DM30 locomotives. The big problem that the LIRR has is the limitations of the C3 car fleet.
Without more cars (leased from elsewhere or new multilevel cars) any added locomotives will not
amount to much other then to beef up the fleet.

Tadman brings up interesting points about the limited options for resale of the Genesis units.
This will be the same problem for the LIRR when they finally replace the DE/DM30 locomotive
fleet with limited resale value or interest since they were specially designed passenger units.

The huge difference between these more recent passenger diesels and the older models that
they replaced is that they had specific designs for their service lives and would not be readily
adaptable for future use by freight railroads as past units were. That is the problem that many
of us realize here...

no one is even ordering dual modes yet, so your talk of 700 is moot and off topic.
If Conductors are in charge, why are they promoted to be Engineer???

Dutch: I used the 700 series dual modes as an example of where they could eventually go...

With the proposed three agency NYS dual mode locomotive order on indefinite hold any future use
elsewhere is a long way off if at all...Back to the topic...MACTRAXX

I’m also not worried about the Genesis disappearing wholesale within the next ten years, considering there are still ex-Amtrak F40PHs in daily service - some still in as-delivered configuration (the Music City Star units for example.)

Still would like to see a number of P42s go to Altoona for an AC motor/Tier 2 upgrade, since they fill a specialized role unlike any other Dash 8 or Dash 9. I don’t expect any P40s to remain though.

The biggest problem for any Dash 8 unit is the computer system. As long as it is working everything is great. As everyone knows, computers do go bad. The Dash 8's do not use any off the shelf computer system or software. It is proprietary to GE and GE long ago quit supporting it. It is also hard wired in that the software cannot be upgraded or changed without changing the circuit boards. So everything on a unit can be in great shape but if the computer gets a glitch you are screwed. The only way to fix it is to take one out of another unit. Starting with the Dash 9's, GE changed the computer to a slightly more user friendly system that allows the software to be upgraded or changed as needed.

What rough generation do the Geneses fall into - Dash 8 or Dash 9? Does that change depending on if they’re P40s, P42s, or P32ACDMs?

Dash 8 technology, and all electric parts are getting scares not just computer .

Huh, for some reason it didn’t occur to me that P40s are still in daily service, but I’m sitting right next to ALX watching 97(30) depart behind P42 #206 and P40 #824.

P40s still ply the rails. Not just on Amtrak trains, but CDOT's commuter routes as well.

There are quite a few of them still running although they have been upgraded to the same spec as the P42’s. I know the auto train is one of the more common trains to catch them on.

They were all out of service at one point, so you're not losing your mind. Around 2014 some were rebuilt. I could be wrong but it seems it was very timely, as the trucks cracking problem arose shortly thereafter.

Wild speculation
1. Failures of P-42s have been great this past week. Just look at the mechanical delays listed on various trains.
2. Anderson talk of cancelling part of SWC and or other LD trains.
3. Most information about the past sale of some locos seems to indicate that those locos are junk?

Could it be that Amtrak is going to be on a track that the P-40s and 42s will have major failures before the Chargers come on line? Thank goodness that the short haul Chargers are already coming on line!

Last week is some of the most severe weather on record. Let's not write an obituary just yet.
