I could be wrong, but I thought the initial impact of the 377/5s coming into service was going to be to send the eight 377/2s back to Southern? Hence we'll need to have nine 377/5s in regular service before things start getting better for Thameslink customers...?
Actually we need 11 377/5 as there are currently six 377/5 and five 377/2 in service on Thameslink. There wont be any additional service until October on FCC. Currently FCC has 15 diagrams so until more than 14 are deliveried its unlikely the current situation will change. When I said good things for Thameslink customers should have added Southern as well as these means thaqt progress is being made and slowly we are getting there.
from what i gather any new delivered 377's are to be comissioned and then sent to cauldwell to go into warm store/shuffled with delivered 377/5's until all the power upgrades are completed, as there is not enough power to have them all running i heard august will be when the power upgrade is completed.
so this presents a couple of question's, if all 377/5's had been delivered on schedule, would they just be sitting in sidings/depots waiting for the upgrade to be completed?
could this be why there are 4 377/5's at selhurst, they may well have been comissioned but just not delivered due to space.
Well any further 377/5 deliveries would not go warn storage, they would release 377/5 so until the 13th unit was deliveried not unit would go into warm storage. Likely the additional units would be used for driver training and having livery applied rather than just sat around.
Your right on the power supplies. There is currently a limit of 11 FCC Electrostars on the BML due to fears of overloading the power supply. The upgrades are due to be completed by 20th August so not that long. Bare in mind by this point only 10 or 11 377/5 are likely to be in service by then.
Currently there are four 377/5 at Selhurst and they none are commisioned yet. Bare in mind they can't commision too many units at the same time as early runs require an additional 377 and extra staff. The original plan was to only commision two at a time so for now two will sit waiting. So give a chance to actually get these units out.
377509
Deliveried on 28th May, failed its first 7 test runs and has been out recently with 377510. This unit was caught up in the recent 377/5 withdrawn issues and likely the last to have the mods fitted.
377510
Deliveried on 15th June. Had a few test runs so far successful.
377511
Deliveried on 1st july and currently awaiting its first test run.
377512
Deliveried yesterday morning so untested as yet.
Nothing been heard of 377506 but 377503 has been seen on the test track at Derby so may be the 11th unit. Also noted at the same time as 503 was an un-numbered 377/5.
Also note that it takes 3-4 weeks to comission a single unit, doing two units may affect this. This should mean atleast a couple of units will be with FCC by late July/early August.
There is a 377/5 returning to Derby to have additional owrk on it. Currently is one of the four units above at Selhurst. Guessing it would be 377509 due to all the problems with this unit.
