No. Trains are often cancelled for unavailable stock as it is.
Just because you might see one or two sat in a depot doesn't mean
they are actually available for service. After the 7/7 bombings,
the Circle has had one train regularly cancelled due to the lack of
that one train.

Surely two Circle trains sustained bomb damage on 7/7? How much stock
was written off?

2 anna bit cars, which equate to units as the other car is useless
without its mate (well, two cars properly bombed and 1 slightly
damaged which was used as the template for the two cars rebuilt).

One Circle line train consists of 3 2 car units.

As with the Irish bomb in the 70s. One C77 unit was provided as a
replacement, one new car and one rebuilt.
