Which one? I used the line almost every day last week and didn't spot any units I didn't recognise. Is it on the west side?Surprised no one noticed the new 7 car yet ....

Isn't work happening at Aldersbrook to lengthen this eventually to nine coaches, possibly by removing a siding or two or did I just imagine that?

345002 is currently at Bombardier as a 7 car
345001 is due back soon to get ready to go south and 345018 is at Melton replacing 345001 as the test unit there.
Only 345002-17/22 are in 7-car formation. 345001 has 345022's extra cars - 345001/2/4 are test units and not in service - everything else is 9-car.
There is no chopping and changing of unit lengths going on.
Could you please tell us which one it is instead of us spending days guessing?There is one more 7 car.....
Is that a 7-car? If so, then yes I imagine it must be.345029 is on the Paddington - Hayes & Harlington circuit today. Maybe this is the unit being referred to?
I thought so too but then saw TIN counters for 9-car 345s start appearing and got a bit puzzled...Sorry I didn't count the number of vehicles but I thought Hayes bay platform can only take 7 cars but I could be wrong about that.
9 car now but I'm not sure about the paperwork...Sorry I didn't count the number of vehicles but I thought Hayes bay platform can only take 7 cars but I could be wrong about that.

That's correct; the nearest two to the main line are 345 026 and 345 045 but I haven't clocked the numbers on the far two yet.
The far two are 345046 & 345048
See post 2804....that's the 4.Does anyone know the identity of the 345s currently stabled at Maidenhead? Apologies if this has been asked previously.
Thank you. I'm sure 2804/5 posts were not on my screen when I posted my query!The far two are 345046 & 345048

6.2 RLU –FLU Swap-Out
As we described in our Period 1 report, just prior to the MTR-CSVP meeting, the ORR decided not to provide a letter of no objection to BT (Bombardier Transportation) and required the train to be re-authorised. BT has reported that it will comply with the ORR stipulation, and has now received the letter of no objection. In anticipation, BT has submitted a proposal to the SVP that FLUs with Y0.256 configuration be approved for both ECS movements to Reading, and passenger services to Hayes and Harlington. For that to happen, the SVP will want to see evidence that:
- A train has completed 1,250 fault-free miles;
- The list of driver defects and control measures is manageable, with a plan for rectification;
- ETCS resets have been eradicated;
- Technical assurance documentation is complete;
- The ORR letter of no objection has been issued (so any approval will be conditional until such letter has been produced);
- The RSSB deviation has been extended to December 2019. (This was extended on 6 June).
The defects and controls issue is the primary issue for us, as BT and MTR-C must agree on what is an acceptable number, and nature of them, to start operations with. This needs to be supported by a suitable rectification plan for dealing with them. The other concern is whether any key defects extend beyond the start of Stage 5A.
Achievement of the fault-free running target remains difficult, as there is a lack of sustained access to the GWML to test and accumulate the miles. CRL is assisting BT in obtaining greater access.
CRL has reported that testing on the Heathrow Spur in the period has produced some good results, but software development remains the most significant risk to the Stage 2-2 programme.
As can be seen from the table, BT’s at-risk datefor Y1.2 completion has moved back by 10 weeks to 25 October 2019. This is due to the need to build an additional TCMS release to manage the issues arising from BT testing, together with the associated assurance approvals.
There is also a lack of clarity about the software authorisation process. This is because of the relative novelty of the software for the approving bodies. Current issues with Stage 5A approvals, the software for which manages simpler technology, illustrate the difficulties of the approval process.
What is the location and status of the fleet now?
Close headway multi-train testing in the tunnels has now commenced with a minimum safe distance between trains, at slow speed, of only 50metres. During July, testing will see the speed of the trains progressively increase and more of the automatic train operation functions brought into the testing programme. Testing of further versions of software provided by Siemens and Bombardier is also underway at the Crossrail Integration Facility located in Chippenham. These tests will build reliability of the software before it is used in the tunnels. The latest release of software is important as it will allow testing of further functionality and allow Bombardier to commence critical assurance activities for the train

I have 345.003,5-17,22,29 in service as 7 cars, but the rest?
To get approved for passenger use they must solve a problem they have with ETCS resets. I'm not sure why, as ETCS is only used in the Heathrow tunnels.
I didn't know that. Its not just a software upgrade then? Is there somewhere this is documented?On the existing RLUs they use a standalone AWS/TPWS system.
