I ran a search for these and can see that the site is pretty saturated with this location, but also everyone's photos are varied enough that I figured I'd add mine to the pile.
Dropped by here recently with @The_Raw @Lenston @Maniac and @obscurity while en route to another location out West. The tunnels under what used to be the Longbridge Plant were used in part to produce engines for RAF aircraft during WW2 and continued to be used for automotive works afterwards. The first section we checked out were the 'Runway Tunnels'.
A set of doors looking away from a workshop area.

..said workshop.
Some of the contents.
A brick lined section.
One of the longer corridors
A small room to one side was full of scraps of cable.
Leaving this section, we were curious about the structures above, some of them were clearly not in use, some we were not so sure about. We headed up some heavily overgrown stairs and towards a building with a large chimney which usually means something interesting is inside. 
Covered by cameras but looking distinctively not in use, we found an open door around the back, all manner of alarms were going off inside unrelated to our entry, we chose not to stick around regardless, a set of 3 Gas fired boilers were in the main building along with all associated machinery.
Back to some more of the tunnels on the other side of the ongoing above-ground development..
A ladder leading up to a ventilation inlet, the top was blocked by some compacted earth but would not be impossible to get in from top side.
No entry.
Generators, rectifiers and batteries.
A slightly flooded entrance, for once I wasn't the one to get my feet wet.
Besides the fact I'd seen lots of this place online, I actually really enjoyed this set of tunnels - many thanks @Lenston as ever.
