Except for the extra Crossrail rolling stock needed to run the extra

Offset by the EMUs not required to run the normal local service. If
they have any sense the Crossrail tunnel will be full size and any
EMU will fit - one would hope.


Except that I doubt Crossrail would want a mixed fleet running through
the central section, so extra Crossrail EMUs would need to be ordered;
remember that the planned signalling system is ERTMS (cheaper to fit
to units designed for it than to cascaded class 319s) and the stock is
likely to have larger doorways than existing EMUs to aid loading and
unloading in the central section.
