I had a a thought about a possible use of the class 317/7s that would not only benefit Greater Anglia but Heathrow Connect as well. If Heathrow Connect take the 9 317/7s and replace their 5 360/2s with them. One can work the terminal 4 shuttle and the other 8 can be double up so HEC will be replacing 5 car trains with 8 car trains. This will allow them to either start to provide 1st class, or they can reconfigure the seating and vastly increase capacity.
I am aware that class 317s can't accelerate as fast as 360s but the scheduling fits 360 services in between 165/166 operated services so acceleration shouldn't be a problem because 165s/166s have poor acceleration anyway. 3 360s are required to operate HEC services and a further 1 to operate the terminal 4 shuttle so if each of these 360s is replaced by 2 317s it leaves 1 unit free (like there is 1 360 left free today), or 2 units left free if the shuttle is only operated by 1 unit.
Greater Anglia can then take the 5 360/2s, and then replace 2 peak hour 8 car 321s (that used to be 12 car when the 317/7s were still around) with 10 car 360/2s, increasing capacity (leaving 1 unit free). The displaced 321s can then be used to make further services up to 12 cars.
Alternatively, the 5 360/2s can be reduced by a car to make them 4 car units and standard with GA's 3601/s so they can be used as 1 common fleet, and then the 5 redundant centre cars can be returned to Siemens to be used in the new LM 350/3s or TP 350/4s as centre cars from 350s and 360s are as near as makes no difference the same, and doing this will save some money as 5 fewer cars will be needed to be built. The 360/2s will be needed to be fitted with 1st class, but this won't be a problem as Siemens are still making 350/360 seats (for LM/TP) and because the 360/2s are already in a base colour scheme (grey with orange doors) they will not need to be repainted, and just rebranded as Greater Anglia.
I know this is unlikely to happen because BAA would not want to swap newer stock for older stock, but what do you think of my proposal.
