Abellio Greater Anglia Class 755s (Regional Trains)

[pompeyfan]

Quite simply they were designed for full DOO. The original offer from GA to the RMT was to roster a guard only on the weekly roster, they were to run anywhere and everywhere DOO if needed. Obviously and rightly the dispute came up with a much improved situation.

that’s poor that they were only rostered up to the weekly sheets, and glad it’s been resolved, but they’ve had a long time to resolve this local door issue, and with the government speccing ever train to be futureproof local door should have been thought of previously.

Indeed, thats why they ended up with an OBS style role like we have on SN. So I'd think if possible they could modify the trains to allow the Guards Key to override the Local Door Closing. If not ensure communication is made with the driver with regard to station assistance.

Indeed that is the way it works, however be it noted GA guards are still that, they still have all safety critical duties and are dispatch trained.

Grim morning on Anglia locals today. BMUs 410, 417 & 422 are the only ones fit for traffic. Three consecutive Lowestoft services are cancelled along with several Yarmouth's

The introduction of new trains are never without their challenges but this must be extremely frustrating for all concerned. I’m surprised that buses aren’t replacing the Felixstowe branch.

So brand new trains are broken already. Not good publicity for Stadler!

tell me a manufacturer that’s introduced a new fleet of trains seamlessly in the last 10 years... I’ll wait

Pretty certain even the 387s and 377/6&7 had issues and they were continuations

Ironic you said that as 4M94 has failed on the branch near Trimley. Felixstowe shuttle now suspended ufn.

Best I can recall were the 379s on West Anglia. Can't remember a great drama, but that may just be due to loss of memory.

Arriving at 8.30am at Norwich station this morning ..only the East Midlands train in platform 1... nothing else in any other platform!
Have they given up?

 

[Meerkat]

Remember the glow of “ooh Stadler, the Swiss will supply proper trains that work”

Even the Germans can’t make new trains work consistently

That's assuming the problem is the trains. Could be a fault with the trains. Could be someone vomited on a train and they haven't been able to clean it up yet. Could be vandalism. Could be routine maintenance not finished in time for start of service due to some issue at the depot (is Crown Point still in disarray or is the rebuild finished). Could be emergent work being found necessary.
Could be anything. We can't assume it's some build problem, particularly as we are talking about units that were accepted into service some weeks ago.
Having travelled on them several times, they are proper trains and they do work.

Stepping up on Londons so nothing for the Ni90 also 0818 & 0833 Lowestoft arrivals caped along with 08+25 cars and 0836 Gym. Not good.

Stadler have, on the continent. Many times over.

But they've not had to launch a trainset with a British-built ASDO and CCTV system before. The people in the know have revealed enough for us to know that that system isn't playing well with the Stadler's TMS, but beyond that we don't know if that's the actual issue delaying usage and acceptance.\

(For all we know GA haven't trained enough people to operate it either, but they're obviously not going to be trumpeting that around...)

Must be short of a (short!) set or two on the London trains?

 

[Alfie1014]

Introducing a completely new fleet was always going to be a huge challenge, especially as they are effectively new types, (though the Aventras are similar to others in the family). That said the big problem at the moment is the fact that the existing rural fleet is leaving the franchise, a 170 is awaiting repairs at Colchester and the lease for the short set locos has expired, this has pretty much decimated the local Suffolk and Norfolk services. Can’t see it getting any better, (don’t forget the 156s are supposed to go to EMR by the December change), unless the Stadlers start improving or the cascades are suspended.

 

[LowLevel]

The irony here being the guards retaining competencies the company were originally determined to do away with is the only thing stopping a complete collapse of the house of cards. Ho hum.

Yes, I was trapped on a 387 at King's Cross for some time when the doors would not release and we were told the train was refusing to recognise it had arrived at the station. The coupling at Cambridge was a thing to see for a while too.

Unless you discount the issue of the door buttons falling off in the early days

 

[Railperf]

So much for Greater Anglia's 'soft' launch! But I am sure it will come good. How come 5 of 8 new trains are out of service? That is pretty serious!

 

[dk1]

Seven accepted but only one not available today so an improving picture. Seems almost all issues have been software related.

No GPS signal. A well prepared driver can manually override with a few seconds delay (as they had to do at Victoria with 377s for years on end before it was sorted).

How secure is the software against hacking while trains are in service?

Any news on leaf fall issues yet? Sitting in 409 on Saturday - light rain had made the rail a bit greasy and it was clear the wheelslip protection was kicking in. 0 to 60mph only increased by a few seconds - so quite effective. How many powered axles on these?

Same on a trip I made last week, could feel the wheel slip protection kicking in, but still easily kept time.
I believe the end bogies are powered, so 4 driven axles per unit.

Not like the 90's which slip so badly in the wet. I do believe the 755's when used through to London all be far more reliable timekeepers in the wet.

Since this is one of my areas of professional expertise, here are my thoughts.
The Software on the Train should be safe from intrusion, I doubt Stadler use a Tesla style global software update method, so no way for a Hacker to intrude. Not sure what systems a modern train has aside from Train Radio and Signalling interfaces. We consider hacking in terms of attack surfaces (methods of intrusion) I would imagine a hacker might hack the signalling system (which is not train specific) but I cannot see there being any attack surfaces (i.e. points of entry) on a train, unless someone gains access to the cabling running through the train.

As far as I know, WSP, Wheel slide protection is for when under braking, It is auto power reduction that decreases/applies traction to a particular axle when accelerating under power and that axle starts to slip.

When the 700s sat down en masse I thought it was said Siemens sent out updates from the office - I inferred this was via a network??
