Think there was more MPD's at Washington at the time than just 523-531, As you had Services W2/W3/W4/W5/W6/186/293/393 and 493 and a few more which used MPD's, And there is no way 8 MPD's could cover the PVR of all those Services.
532 spent some time at Washington in 2010 - https://www.flickr.com/photos/gjm-photog...462375209/
Might worth asking the likes of Gary Mitchelhill and few other older Enthusiasts about 533 to 548, Because you would think that for all those Services the PVR would be over 20 at least, Anyway I have put a post on Facebook asking if anyone knows any more details of the MPD's, hopefully we'll get some feedback.
MPDs 524-542 were new to Washington Depot. All of this is in the notes section for those vehicles.
I'm fairly confident that what we've got on the fleet lists for those MPDs is fairly conclusive.
