The central London tunnels will be built to an increased loading gauge.
The planned running tunnel diameter of 6.2m is nearly as large as the
6.3m RER tunnels in Paris and certainly big enough for most continental
stock.

Any idea what that corresponds to in either W6/8/12 etc terms or UIC
A/B/C? And whether other constraints for those gauges (or kinematic
envelopes or whatever we're supposed to call them now), like radius, will
be met?


The biggest constraints that prevents the adoption of continental
stock for Crossrail (or anywhere else in the UK with oversize
structure gauge) are the dimensions of British platforms. Our
platforms are much higher and come closer to the rails.
