So it looks like the crazy old Crossrail is going ahead! Coooooool!

Question is , will they do the sensible thing and build the tunnels
to
UIC gauge so there is at least the possibility of running dedicated
double deck trains through them alongside normal UK trains , or will
they build it to the hopeless 19th century UK loading gauge and then
complaints about undercapcity start to surface a few years after
opening?

Double deck trains don't work on frequently stopping lines
with overlapping journeys like crossrail is expected to be.

The Germans tried them in Munich as a solution to their
capacity problem and promptly took them off again as they
added no extra capacity.

How can they add no extra capacity? I don't follow.

Because the extended dwell times at the stations
whilst people get off through fewer doors means that
a smaller number of trains can be scheduled through
the tunnels each hour.

True. Double decker trains are mostly a solution for trains
terminating at a big terminal, since most people will be getting off
at just one stop.- Hide quoted text -

They seem to work quite nicely on the RER in paris.

which only proves that they work in Paris
