Class 315 (data is for 4 cars, so doubling up)

636 seats
226 standing
862 total

Class 345 (data is for 9 cars, rather than 10 - is the 10 car set up
for later?)

450 seats
1150 standing
1500 total

(which is a pretty significant total increase....)

You did better than me on the 315 capacities. I found seating but not
standing capacities.

the 345s will initially be 7 cars when they run into Liv St prior to
May 2019. From that point they need to be 9 cars and will have the 2
cars re-inserted for running through the tunnel. I think when
Crossrail takes over Heathrow Connect in May 2018 that those trains
will be 9 cars but they'll run solely on the surface at that time.
There is no 10 car design. The 345s are extendable to 11 cars and
the central area platforms are all built to that length but may need
finishing / fitting out whenever the 11 car decision is taken.

Timeline

May 2017 - 345s enter service Shenfield - Liv St (surface) 7 cars
May 2018 - Crossrail takes over Heathrow T4 - Paddington "Connect"
service. 9 cars.
Dec 2018 - Paddington (low level) - Abbey Wood service starts. 9 cars
May 2019 - Paddington (low level) - Shenfield service added. 9 cars
Dec 2019 - Full through service Shenfield / Abbey Wood - Heathrow /
Reading. 9 cars.
Sometime in the future - trains possibly extended to 11 cars.

The point of the 9-car Crossrail Aventras is that they are the length of a
10-car train of standard stock, e.g. 315s, which are 20m long. So the class
345 cars will be ~22m long, making a 7-car train similar in length to an
8-car class 315 formation.

These lengths are a bit approximate as was discovered when they wanted to
run 12-car trains of class 365 stock from Cambridge to King's Cross.
Platform 1 was supposed to be long enough for 12-car trains. It is, but only
for class 317s. 365s are that little bit longer and wouldn't fit between the
starting signal and the scissors crossover, hence expensive platform
lengthening work.
