Physical description
Run number plates used for the vehicle identification system used in the AVM. Item was pushed into a slot of a reader which then recognised the identification through the series of holes on the left hand side. Fitted with metal strips, riveted on, to enable the card to be slotted into the holder by the crew member and then withdrawn when not required. Understood that the tram carried one of these at one end and then another without the holes at the other end.
Number has been engraved into the plastic sheet and then painted in black.
Used to identify the depot and "run number" or timetable that the tram was running on, two in each tram, to enable monitoring by inspectors and crews. System introduced by the MTA during the second half of the 1980's.
