Instrumentation Development Section.
Though 'section' is the one word I'm not 100% on - but it's too long to be 'Unit'.
The pic is sharper in the MR Special on Derby, and the title is quoted in the OPC book.

A colleague tells me the unit was hired in by LU for a period when they didn't have their own track recording train available. Nice photo.

I am intrigued to know whether the dmu was running on its diesel engines or was being propelled by an LU battery loco

I'd imagine that it was running under it's own power, but possibly with restrictions on how much fuel it could carry due to fire risks.
When the TRU (yellow sprinter) run's in the Mersey Rail tunnels, this is the protocol.
I'm saying it's running under it's own power, as I don't think LUL had any "Vacuum Braked" loco's (by this time anyway), that could have been used to haul the unit.

Between December 1984 and January 1988, before the LUL Track Recording Vehicle entered service, Lab 5 was used to collect track data for those sections of LUL track over which the vehicle was in gauge.
The unit was self-propelled and driven by a BR driver with a LUL pilot.

In October 1976 Lab 5 was shipped to Zeebrugge to carry out a track survey in Holland for an ORE project.
