There does appear to be huge reliance on the timely delivery of an electric spine in the proposals. The much publicised delays and overspends in the GWR electrification, with knock on effects to the large MML and TPE programmes has the risk of pushing the delivery of an East-West Rail link into the proverbial long grass.
But while electrification as a long-term goal is desirable, is it essential to deliver the train service ? Indeed, couldn't an alternative solution deliver the passenger numbers and route growth potential which in the long-term would justify electrification.
There are 4 proposed services:
(a) hourly all-stations service between Bedford and Bletchley. This could probably be extended to MK. The existing Class 150 and 153 stock appears adequate, although it could be transferred to an expanded Chiltern franchise, with depot facilities at Bletchley. A Sunday service should be introduced.
(b) hourly Bedford to Oxford semi-fast service. Journey time 61 minutes.
(c) hourly MK to Oxford semi-fast service. Journey time 41 minutes.
With the GOBLIN route electrification scheduled to be completed in 2017, this should release up to 8 x two-car Class 172/0 units. This could provide sufficient stock to operate (b) and (c) above.
(d) hourly MK to Marylebone semi-fast service. There is already an hourly service from Marylebone to Aylesbury Vale Parkway station, so units operating this should simply continue to MK. If additional DMU are required, then perhaps an additional LHS with MK3 coaches can be used on the Oxford or Birmingham services to release the additional DMU.
Now there will still be a need for infrastructure work before these services can be introduced but track, signalling and platform alterations should be much simpler and therefore be possible by 2019. Electrification can follow at a time when the logistics and funding become available.
