Potentially not until one of the 6x remaining 172s either fails or has to be withdrawn?
There has been a tweet this afternoon saying that the decision, i.e. seeking approval to operate, the 4 car 378 should happen next week. The 378 was doing PTI checking work 2 nights ago. The Line user group have also said that 710 265 was out on testing on the GOBLIN recently. That's the first time in weeks.
Has the 4 car 378 actually run into the Gospel Oak bay platform? Same question as to whether a 710 has done the same. None of the paths I've seen have included running into the bay which has caused some rumours to circulate as to whether 4 car EMUs actually fit in there.
4-car fits in to gospel oak. Currently a 172 stays in gospel oak overnight and with the various blockades it is difficult to have it in the right position for the morning start up.
Is this for real - they must have known for ages that the new units couldn't be accommodated surely?
The new class 710's are only 4, not 5 carriages. The class 378 stop-gap replacement was 5 carriages and thus had one removed. Hope that clarifies things.
Err a 5 car 378 can certainly use Barking platform 1 because the very first electric test train went in there. Anyway the platforms at Barking are very long and can certainly take a 4 or 5 car EMU.
It is other stops on the line that have constrained platforms but the key constraint is Gospel Oak bay platform. Thanks to Electrojuniper's earlier reply we know 4 car EMUs can fit in there. A 5 car unit could not. Also the platforms at Blackhorse Road are only long enough for a 4 car train - they were not extended or modified during the blockade. Walthamstow Queens Road also had to have its platforms rebuilt / lowered because the track was lowered. The platforms there are only 4 cars long although parts of the disused old platforms remain in situ and could be modified if we ever get to the point of needing 5 car trains. South Tottenham is also constrained to just 4 cars long. Other stops have old platforms still extant but only a short section of each was refurbished to allow 4 car EMUs to fit.
Back in the good old days 4 car steam trains ran into Barking given the run round there would need to be a length of at least 6 or 7 coaches to allow the steamer to pull up to the points
South Tottenham must have been an intresting one to lengthen with track infrastructure at both ends.
Gospel Oak is a major constraint - it is OK with four car trains but five car might need selective door opening.
Unlike other stations this platform is relatively new - in the old days the trains went to St Pancras, not here!
I don't think Selective Door Operation will help at Gospel Oak as the train will be beyond the starting signal.
As for St Pancras operation not in my lifetime. Kentish Town almost certainly.
From the other thread:
This does not sound very resolvable by January 26th when the first 172 is leaving.
