Also, 12 Crossrail in the peak hour? I thought 16tph were going to
Shenfield?

The plan is 12 Shenfield and 12 Abbey Wood in the peak. Actually I think
there is a case for 16 Shenfield and 8 Abbey Wood in the high peak, though
there is a need for enough trains from West/Central London to Canary Wharf.
It might actually be possible, if enough high peak trains from Shenfield run
to Crossrail to do away with the Shenfield to Liverpool Street terminus
trains. Then on the approach to Liverpool Street the Electric Lines could
become the Mains, the Mains could take some Main Line trains, trains via
Tottenham Hale and Stratford, and, from Bethnal Green, some trains off the
West Anglia Lines, leaving the Suburban pair mainly for Enfield, Southbury,
and Chingford.
