Lone 80 Class DVT, No. 879, sits on an isolated section of track only accessible by traverser.   These photos were all taken on the 26th of July 2014, with permission from Translink.   Oh, and in case you were wondering, the only Thumpers on NIR that aren't in York Road are: 
The Sandite Set usually sits beind 8090, but as aforementioned, was recently moved into the main workshop.
Lone 80 Class Power Car, No. 8090, sits alongside a C3K unit in ''The Motorway Siding''. This unit is a spare for the Sandite Train.

The passenger area of 8097. 
Of course, it's been a very long time since the unit actually carried any passengers.
After 80 Class power car 8097 suffered irreparable engine damage a few years back, it was used as a trailer car and fitted with sandite-spraying equipment and now spends its Autumns trekking up and down the NIR system as part of the Sandite Set.

The condition of the interior is a bit worse for wear in some places.

458 ''Antrim Castle'' has been in store in this siding since 03/02/2013.
York Road Depot is NIR's main enginering base, and houses much of NIR's stored stock in addition to maintaining the active fleet. 
​Although in its heyday York Road was teeming with Thumpers, nowadays only a few members of the 80 and 450 Classes survive within the yard.
