I guess it was lucky (in so much as these things can ever be lucky)
that the line wasn't much use at the time of the Moorgate disaster,
since that meant the train was carrying its seated capacity of 300ish
people rather than its design capacity of 800ish...
If my memory serves me correctly (questionable) the Northern City line
as it was known only used 4 car sets.
