It might be that the programme to do the civils work is done to the
original schedule and then you phase the fit out and commissioning
more slowly. This may also allow any rolling stock procurement to be
put back so that co-ordination with Thameslink (common fleet) can be
achieved and the supplier has a long production run but the cost is
spread / financing made easier.

Are the requirements for the trains for TL and CR similar enough for a
common fleet to be possible? Apart from the whole dual-power thing,
which i assume would be easy enough to leave off the CR trains (maybe
except a few, so there's a reserve that could be used for TL at short
notice). What about seating plan? That could be varied between batches,
S-stock style, if necessary. What about the engines and suspension? What
about signalling? TL isn't using ERTMS, right?

I don't think they will have any engines

AIUI the intention would be to leave open the possibility of using the
same basic body shells, traction equipment, etc, to get a better unit
price, but still have the choice of different internal layouts and
fittings - things like seats, luggage racks. Crossrail won't have
tiolets but Thameslink will.
