I thought the W&C tunnels were big enough to take regular stock...

No, in fact they had to be enlarged slightly to take the 92 stock.

Thought I had vague memories of NSE trains
running on the line before the management
went over to LUL, but could well be wrong.

They were certainly NSE trains, but approximately tube gauge. The current 92
stock are still in NSE livery.

You might be interested in something I put together a few years ago.
