Before the new trains entered service, there were 94 units, making 47 two-car trains. There will be 55 of the new ones, but each train will need three units so there will be 149 trains, that could make 49 trains with two spare units.
How many trains were used in service in the peaks before all of the upgrade work started, because there will be two extensions, and two extra trains doesn't really seem enough?

oh yeah.... i'd never done the maths before but no that doesn't make sense. they can't run a full service to bank and tower gateway AND the stratford international extension with that many trains. maybe more units have been ordered.... it's hard to imagine they would do without it being big news.

Before the 'serious' work started at the end of June 2008, the stock requirements Mondays to Fridays were as follows:
41 trains - 82 vehicles - morning peak
40 trains - 80 vehicles - evening peak

I think there will be enough for Stratford International because not all trains will be 3-car at the time it opens, but it doesn't seem like there will be enough trains when the Tower Gateway - Beckton and Stratford International - Beckton services become 3-car. |

Before the 'serious' work started at the end of June 2008, the stock requirements Mondays to Fridays were as follows: 41 trains - 82 vehicles - morning peak 40 trains - 80 vehicles - evening peak Woolwich Arsenal: The Woolwich Arsenal extension needs an extra train in service, so if the services were running normally at the moment, that would be 42 trains in the morning peak. Stratford International: developments.dlr.co.uk/extensions/stratford/service.aspsays that Stratford International - Woolwich would take 21 minutes, and it would take 10 minutes to Canning Town, but I can't work out how many trains they would need as I have no idea how often it would run in the peaks. I guess each service from Stratford International would run every 10 minutes off-peak. |

The DLR hasn't been running "normally" since the beginning of October 2008. With the Woolwich extension now open, the current stock requirement (still on a reduced schedule) is 43 trains AM peak and 41 trains PM peak (86 and 82 vehicles respectively). Next timetable change - when Tower Gateway reopens.

Next timetable change - when Tower Gateway reopens. I thought that the DLR hasn't run normally since Tower Gateway closed. When it re-opens, the Beckton trains should start running to Tower Gateway again, but that would mean there would be several more trains in service than last year (before the work started). Why is this? I think it will be less confusing once the next timetable change happens. |

When Tower Gateway closed, a 'normal' service was provided over the rest of the line (apart from when there was single line working on the south leg during the summer). AM peak service from 26/8/08 was - 3½ min BAN-LEW, 14 STR-CRO, 14 STR-LEW, 7 BAN-KGV and 7 CAT-BEC (which was of course the former TOG-BEC service). The evening peak was similar except that the service from Stratford was 7 mins STR-CRO with no Lewishams.
The current service AM peak is 5 BAN-LEW, 5 STR-LEW, 10 BAN-WOA, 10 CAT-BEC and (in the main part of the peak only) 20 BLA-WOA, giving Woolwich 3 trains every 20 mins.
The evening peak is 5 BAN-LEW, 10 STR-LEW, 10 STR-CRO, 10 BAN-WOA, 10 CAT-BEC and (in the main part of the peak only) 20 BLA-WOA, giving Woolwich 3 trains every 20 mins.
The reduced services are such that the services are currently based on a 5/10 pattern instead of 3½/7. Don't know when they will go back to the latter.
BLA = Blackwall, hope the other codes are understandable.

This says that the Stratford branch is actually getting more trains now than before the 'reduced services' started (Stratford trains run every 5 minutes now instead of every 7).
What is the reason why the Stratford service is different in the evening peak?

Correct that STR has a better peak service under the 'reduced' regime!
The PM peak STR service has been 'different' from the AM since May 2000. Don't know why, but possibly because of different peak traffic flows?
