Here's a copy of Rudy's old (2017) roster from further up the thread - he was working with M&E and I believe has since left. I've taken a swing at some updates, from what I saw last year and have read online:
C424 #18 - Sold - IL rail museum
C424 #19 - Sold - Tri-State HS
SW1500 #20 - In service @ morristown
RS1 #21 - OOS at Whippany, RRPX-owned
GP9M #22 - Stored somewhere around morristown
GP7u #23 - Stored somewhere around morristown
GP7u #24 (former # BAR 21) - Stored somewhere around morristown? Or is this the one that ended up on the Housy in CT? If so it never made it to home rails.
GP9 #25 (former #BAR 79) - Stored somewhere around morristown?
GP7 #100 - Still stored @ the old Wharton & Northern yard.
FL9 #485 - Scrapped?
FL9 #488 - In Morristown?
FL9 #489 - In Morristown?
SW1200 #557 - In Morristown RRPX-owned (FOR SALE)
SW1200 #559 - In Morristown RRPX-owned (FOR SALE)
SW1200 #563 - Still stored @ the old Wharton & Northern yard. RRPX-owned (FOR SALE)
GP9 #764 - In Morristown RRPX-owned
M420 #3573 - SOLD
C424 #4204 - SOLD - in Scranton if I recall right
Plymouth #7299 - SVC in Morristown, owned by the Military Transport Association
This makes the RSI 21 the only Alco left on the property. I'm glad the other Alcos got out, given how they cut up some of the others not on this list (CP 4321 comes to mind).
The ones listed 'FOR SALE' were on sale as of Rudy's update I would assume the same holds true today.
Given the surplus of more modern locomotives on the market via class 1s, I'd be a little surprised if any of the GPs or ex Amtrak SW's find buyers.
I didn't include the 'new' Ex NS units on this list.
Was #22 the one that was supposed to get a sulzer engine? The last I saw of it was two years back, located on one of the old sidings along the route, buried deep in a cut of derelict passenger cars and one of the FL9s (maybe 485).
I'm surprised the RR is hanging onto all the old passenger cars tucked into old sidings, considering the rent they could make off storing freight cars as other short lines are doing.
