Hope you don't mind me asking a few quick questions about the ELL, given I travelled on it for only the second time today and got to thinking about a few things.
1) How many trains are needed to run the service? It's 12tph I think (?) and they have 20 378/1s, plus the 378/2s (225+) to choose from?
2) Have any of the old 378/0s ever ran in passenger service on the ELL. I know they can do as they're dual voltage. If not, are they ever likely to?
3) Is platform 2 at Dalston Junction ever used? The few times I've passed by, it's always empty with the train to New Cross sitting in platform 3. I assume once the Clapham Junction service starts, they'll do like they've done at H&I and have one platform going to one destination and the other going to the other destination?
Danke.

I'm not sure how many are needed, but they only have the 378/1s and six 378/2s, 378232-234/255-257. 378225-231 are at Willesden. 2) Have any of the old 378/0s ever ran in passenger service on the ELL. I know they can do as they're dual voltage. If not, are they ever likely to? I don't know if any of 378201 - 224 have run in service on the ELL, but some were used for testing when they were 3-car units. It's possible that they will be swapped with the other 378/2s once the Clapham Junction - ELL service starts, but not likely unless a unit needed to go to New Cross Gate depot for some reason. It's more likely to happen if the connection for empty stock at Highbury & Islington is ever brought into use. 3) Is platform 2 at Dalston Junction ever used? The few times I've passed by, it's always empty with the train to New Cross sitting in platform 3. I assume once the Clapham Junction service starts, they'll do like they've done at H&I and have one platform going to one destination and the other going to the other destination?. Platform 2 was used for one of the services before the extension to Highbury & Islington opened. As only 4tph is reversing there at the moment it isn't needed, but I'm sure it will be used like you said when they start running to Clapham. |

378214 (formally 378014) was used as a 3-car for testing purposes mainly within the depot and was used one time in passenger service during the preview service in April 2010 due to non-availablity of other units.
Platform 2 at Dalston is used currently for Empty Coaching Stock runs between NXG depot and Dalston. This may be for a unit which is being tested following maintenance or for training purposes. The platform is also used in the event of service disruption (i.e. suspension between Highbury & Dalston Junction) or to terminate a Highbury bound train which has developed a fault (although trains can turn around on all platforms at Dalston). Once the Clapham Jct service starts, it is envisaged that the New Cross will depart from platform 2 and the Clapham Jct services will depart from platform 3 but this is yet to be confirmed.

1) 21 units are required to cover all diagrams, with at least one hot spare in the Berthing Sidings ready to come out if required. There are 25 units based at NXG at the moment, 135 through to 154, and as of Saturday when I was last in, 233, 234, 255, 256 and 257. This then allows 3 others to be under maintenance etc.
2) 378/0 were dual voltage 3 car units. These no longer exist. 378/1 were always 4 car DC only. 378/0 then became 378/2 once they had an extra carriage added.
3) Platform 2 at the moment is used for New Cross trains terminating at Dalston and then becoming ECS back to the depot. You can see these late in the evening, the CIS screen above will show "Not In Service...........25mins" etc. Also the new weekly two morning PIXC busters terminate in Platform 2, then ECS back to depot.

Interesting questions, and others like redbond and 378Driver are more informed than me.
378/0s as 3 car sets did not normally operate on the ELL, but after conversion to 378/2s I recall one or two going briefly to New Cross so that crews would have some experience on the dual voltage types.
However once the batch from 225 to 234 were delivered, several of these went to New Cross. Could any of our drivers confirm which did do a stint at NXG depot and then went back to Willesden?
I concur that the current allocatio is: 201 to 224, and 225 to 232 are Willesden sets, while 135 to 154, plus 233/4 and 255/6/7 are NXG units. When last doing a short trip I saw all the dual voltage units, so the newest 3 are in traffic.
Platform 2 at Junction has been used, and doubtless once there is a fourth destination it will come back to regular use. I have also seen it used for the 'hot spare', not just the ECS turns.
But I would like to ask a question. When Clapham Jct from the SLL is open, will the 25 units be sufficient to provide the full service. I'm assuming the full round trip to CJ will require 6 sets. So will there be sufficient sets to run the post December 2012 timetable?

This was briefly touched on in the "Shiny New 378s" thread. 21 units are used in the current timetable. I do think that either New Cross frequency will be dropped or a couple of units from Willesden will have to come over or both! (all currently speculation although I've heard the New Cross rumour a few times).

I've been told by a TfL manager that the New Cross frequency will not be reduced as they wish to provide 16 trains an hour through the core section (Dalston - Surrey Quays) throughout the majority of the day. However this will be subject to review once the Clapham Jct services start to see if the demand required is necessary. There is also talk of stabling units in Clapham Yard Sidings but this is yet to be confirmed. At present, there are enough units based at NXG to run the Clapham Jct service but we may get an extra 2 from Willesden to act as hot spares.
