This is what the inside of a tube (underground) carriage looks like, gutted for refurbishment….
@TheBreadmonkey They’re pretty much hand built, no two carriages are alike. It’s a team of skilled workers who make every panel to fit, teams of electricians running cables and terminating them.

@j3di

So these were sent to me by my Brother in Law who's currently working on them! It's pretty interesting.

@TheBreadmonkey From my time at Washwood Heath, Birmingham. Testing Pendolinos at the end of the production line. So coincidentally the same line where Jubilee tube trains were produced I think.
@j3di @TheBreadmonkey An alternative view from when I was dispatched to LU's Ruislip depot to weld some brackets on the underside of some of their wagons.
@DJDarren @TheBreadmonkey The mucky side!
@j3di @TheBreadmonkey And then some. Had to do some significant grinding to get to good metal.
