I don't know if this programme is new to UK TV or a repeat, and even
if it is new, whether any of the content will be new to denizens of
this group, but Channel 5 has a documentary entitled "Building The
London Underground" at 8pm this Wednesday. It's described as, "A
fascinating look at the great engineering leaps that built the London
Underground, the biggest metro system in the world." The picture used
is certainly up-to-date:
