I think 'deep' sums it up. Very much a serious episode on the whole since that was the main 'theme' of it. The warning that came before the episode was very valid too. Possibly not the sort of detail I thought they would show on TV to be honest.
Something that I noticed - when the tube worker was going onto the track to test whether the traction current had been de-energised again, I'm sure he actually touched the 4th rail as he climbed across with the testing kit (given how high it is off the floor at that point). Was I imagining things or did he actually do so to help him get across it?
On a lighter note, was good to see how the staff kept spirits up by getting everyone on the opposite platform to blow their horns/whistles etc - I guess it helps keeps tensions from running too high with people wanting to get home, some of whom have probably had a few too many :P

I wonder if this series could end up having the same effect for the staff featured as it seems to have done for the Stobart drivers who have been on Trucks & Trailers....they seem, in some cases, to have become celebrities!
hock:
(and they hit the nail on the head too - it's just an interest not that different to football etc, just less socially accepted 
)
