Where would they get the drivers and trains from at such short
notice?
(We have to have at least 2 weeks notice of change of duties).

Don't they have some extra stock available? (above number needed for
normal peak hour service?)
Is there any emergency procedure to recall staff to work?

The other lines are operating at full capacity in the peaks so even if
you had spare trains and drivers they couldn't be fitted in with the
normal peak service.
