Here are a few pictures I took recently on my own errands around TC (as we called it) - to record its closing BBC-owned days. It looks pretty weird and gloomy. But it's a place to get things done, even if it is a bit Kafkaesque when you stop and look.
Welcome to TC, through the Frithville Gardens entrance (above).
Inside the donut.
Temporary tape storage (above), for Current Ops (below). This is where you take your finished programme to get it "into the system". Once there, if all the paperwork has been done right, it should get transmitted at the appointed hour.
This button looks as though it would work, but the escalator hasn't for years.
Goodbye, and back out to Frithville Gardens.
I've got more pics of the deepest recesses of Television Centre here.
