Greater Anglia Class 755s (Regional Trains)

[TRAX]

They "look European" (whatever that is supposed to mean) because they were designed by Nose, which is a Swiss design company. It also isn’t a design exclusive to the UK.

 

[MikePJ]

For all we associate Jacobs bogies with "continental" trains (mostly because of TGV and its derived designs, I think), it's worth noting that Gresley was an early enthusiast for them on the LNER. The Gresley Silver Jubilee coaches, which were designed to match the new A4 Pacific locomotives, consisted of two articulated pairs and one articulated triple, making for seven coaches with ten bogies.

There have been photos of one in the wild, but I haven't seen any footage of it on the test track at Derby yet. I think Anglia are rightly aware that the 710 delay means 720s are not forthcoming any time soon so are focusing on the trains that are actually visible out testing on the network and have a good chance of actually being in service this year.

One would hope (maybe over-optimistically) that once the software issues on the 710s are resolved, it ought to be quick to apply the fix(es) to other Aventras. Loading updated software should be quicker and easier than physical re-engineering (like the Hitachi windscreens).

 

[samuelmorris]

Perhaps but the issues the 710s have experienced seem quite geographically specific, there may well be issues thrown up by certain parts of the GEML that weren't encountered during LO testing.

 

[Charlie Smythe]

Ordinarily speaking, yes, hence why they aren't commonly used in the UK. Splitting the unit into six coupled sections, however, plus the lighter weight of modern designs, evidently means they can get away with it. That said, there were suggestions that the 755s would be given a lower speed limit on certain sections of track in rural areas due to the higher axle weight. I don't recall if that's going ahead.

How heavy is a 775? There aren't any kind of specs sheets or documents that I can find.

This it the spec sheet Stadler have on their website for the 755: https://www.stadlerrail.com/media/pdf/feabmu0916e.pdf

But it doesn't have vehicle weights!

The data for the 4-car Swiss EMU version linked from this post - https://www.railforums.co.uk/thread...adler-flirt-trains.148431/page-2#post-3030276 - is 124 tonnes total train weight, so about 31 tonnes per car (average). A *guesstimate* might be around 150-160 tonnes for the 4-car 755, assuming the power car is about the same weight as a passenger car?

(The UK bodyshell is smaller width and height, so might be a bit lighter, but I'd expect the other components to weigh much the same as the Swiss version)

Loading updated software should be quicker and easier than physical re-engineering (like the Hitachi windscreens).

Except if those software updates also require hardware modifications.

Also the LNER third rail Tyneside Electrics trains in circa 1937 were articulated - I feel sure they were also articulated twins, like the present-day Tyneside metro trains which largely ply the same routes.

The Hamburg U-bahn DT4s[1] (and probably DT5s as well) are also like that - basically a pair of 2-car articulated units permanently coupled and with no cabs in the middle. Most of their previous sets are just 2-car articulated units with the cabs. FWIW it actually seems quite a popular layout on balance.

[1] DT = DoppelTriebwagen - "double multiple unit" - which seems to describe the bogie layout as well!

(There's also the famous Gresley quad-art suburban stock, but let's not get too far off topic, eh?)

a 755 is due to move to Cambridge tomorrow for testing//commissioning, unit is due to stay there for 4 months and will eventually be joined by 4 other units.

Exciting! Looking forward to seeing it.

Believe this will be the move/path for the unit.

Is it running under its own power, or being dragged? Presumably the latter?

happy to be corrected - loco hauled drag I would have thought, 37800 being the loco for the job.

It doesn't look like it's timed for 45mph Lakenheath-Ely North.

 

[Defiance149]

Anyone know which Flirt worked to Yarmouth overnight last Wednesday and Thursday please, 755405 presumably?

 

[Shunter_69]

406 is in the pics I’ve seen. Not sure if that was one day or both.

Is the nose cover off just for testing or will they operate like that in service?

There is no nose cover!

 

[samuelmorris]

What nose cover? Looks normal to me.

I thought the coupling would be covered when not in use. My bad!

 

[jopsuk]

couldn't see the unit at Cambridge, I guess it had been shunted into the shed? There was an ROG class 37 in the reception sidings.

That combination is quite a picture!

Not sure if this has been covered previously but one thing that concerns me about Stadler units is their crash worthiness. They've been involved in a few accidents on the continent and never appeared to stand up too well. Maybe it's the nature of the incident and any other train would've suffered the same damage and sure they meet modern standards but would still rather take my chance in a mark III than one of these. Perhaps those in the know can prove me wrong?

 

[MikePJ]

I managed to catch 37800 and 755407 at a level crossing near Ely whilst out for a walk today:

The Stadler FLIRTs comply with the latest most stringent crash worthiness regulations, the Marks 3s do not (through grandfather rights)....
