There isn’t really much time! The 153s turn into pumpkins at the stroke of midnight on 31/12/19 and the 156s and 170s are needed elsewhere by the same date.

There will surely have to be derogations? There will for a lot of TOCs. What are EMR going to do about their 153s, for example?

i am seeing great Yarmouth to Norwich cancellations due to a train fault. Is the 755 or the 37's that have failed?

Replacement with the nine Anglia 156s and five 170s from ScotRail was the plan.

37s looking very smart at Norwich, but dead as a dodo. 755s working two of the three Cambridge diagrams, haven't seen the third.

This morning 417, 418, and 413 were working NRW to CBG, 413 has gone off for refuelling to be swapped with 409. 417 has also come off for the same reason being swapped with a 170.

Have just disembarked from 409 at Thetford off the 1309 ex-Cambridge. On the other platform, the 1340-ish ex-Norwich (1413 at Thetford) was also shown as 4-car (i.e. a 755) as I left the station.

First impressions: Very nice indeed!

According to RTT, it arrived at Chester 30 minutes early. Unless the kettle conked out and was replaced with one of WCRCs shabby looking 47s...

Indeed, the Duchess is still sat at Norwich with a valve issue of some kind. The tour left at 0655 with the 47 on the front.

The H12019 Stadler financial report mentions possibility of penalties related to the Greater Anglia deliveries. Further media reports indicate that there are quality issues with components from a British-based supplier/subcontractor, which is resulting in delayed acceptance by GA (but Stadler are ultimately the ones with the liability in this case).

Are those the camera issues, or something else? (Speaking of cameras, I would've thought they'd have a lot of experience with cameras... but I'm having trouble finding photos of any other Stadler unit with external cameras. I know the Swiss ones have cameras inside the vehicle for door-monitoring, but I have no idea about other units.)


The door discussions in this thread are confusing me. Indeed there's one door per 16m, but they're double-width doors. At least on the continent, people can board and disembark side-by-side through such doors - so I don't see why these would be slower, in fact you'd think they'd be faster. From what I can remember us Brits aren't twice as wide as continental Europeans?

The door discussions mostly pertained to the 745s from back when this thread discussed both types. There are of course more doors on the 755s than the DMUs they replace, but on the 745s the opposite is true as the 379s have two double-leaf doors per carriage, the 745s only one.

Ah, silly me - I was indeed thinking of DMU's - and the Mk3 sets. Completely forgot about Stansted Express.

Speaking of adding/removing doors, which was also mentioned upthread: I know that Caltrain are looking at installing plugs for some of their doors (Units being built with doors at two levels, but the higher level isn't going to be needed for many years if ever) - so it would be possible to add/remove plugs. But I suspect they're leaving things like door mechanisms in place (and those protrude into the cabin a bit).

The Stadler bodyshells look like one big unit, into which doors/windows have been cut, see e.g. the second photo in the link below. So cutting another door into the unit might not be that hard:
http://www.dawlishtrains.com/stadler-class-745755.html
But with the placement of the existing door vs where the non-Jacobs bogie is, I don't think you could come up with a sensible door position. Even if you were starting from scratch it looks tricky, compared to the all-Jacobs european sets where you have much more flexibility in terms of door placement. And of course, making that kind of change is going to be expensive and involve a lot of work once the train is already constructed.

I don't see it happening to be honest - despite the quality of the Stadler product, most of the stock procurement for this franchise was done on a cost-centric basis. The expense of modifying those units would nullify all the cost savings made elsewhere.

755s are slower than 170s for dwells though, certainly.

Agreed, having one door /side helped reduced costs and having it in the centre means placing a second elsewhere is not obvious especially with shorter cars and articulation.

The doors are not in the centre.
You'd lose a lot of seats with more doors. I think they're about right.

On the 745: they effectively are: 5 windows one side, 4 the other. (With the exception of the driving units, where a few frames are taken up by cab and electronics.)
On the 755: indeed, but 755's aren't running on the routes where 2 doors would be needed?

755s are slower to clear passengers than 170s, but only place I've seen this being particularly so is at a terminus station so not really a huge issue.

I think the only other option is semi-permanent coupling to the 156's and run them as 3-cars all day, providing extra capacity via a derogation or dispensation. Hence 153's cannot operate on their own from 1st Janauary 2020 lol. Are Greater Anglia's 153's going to EMR? Hence I've heard they have found a new home.

Despite only having one door per side per carriage, the circulation area in the vestibule seemed pretty good to my eyes, which should help.

Yes certainly at Ely the other day the "short" end of the coach emptied out and people started boarding that side of the door whilst there were still people disembarking from the other end of the carriage.
One odd thing I've noticed with the door is that if they shut of their own accord, the step doesn't retract. So you get another (shorter) hustle alarm before the step retracts prior to departure.
Also, it would be sensible for the steps to deploy as soon as the doors are released.the door doesn't start to open until the step has contacted the platform. I had people stood behind me tutting because they thought I was too dim to press the door open button properly.

Yes the step does not retract until the driver or guard has shut the doors for departure. Like a lot of new stock, the doors do close after a set time 60s or so? I didn't time it. This is probably to preserve temperature levels within the vehicle. If the doors are open when driver/guard shuts them for departure, then the doors close and steps retract together. If the doors were already closed, you hear the step retracting independently.
I guess this saves wear and tear on the step mechanism too.

It also prevents, when the doors are opening and closing to maintain temperature, risking the doors being reopened when half-closed by someone attempting to board, finding the step half-retracted and missing their footing. It's the only sensible way to do it really.
