Just been a trip on it. I have to say I'm rather impressed. Much better than I expected.

The interior looks great, a real feel of quality and much better than the 700/707. The seats are a definite upgrade from the standard ironing board as fitted on the 700/707/387 etc and really do feel a bit wider. There is a small spacer between the seat backs. Just to put into context, you can travel from Peterborough to Brighton in worse seats with worse legroom. And no charging points.

Legroom in the airline seats feels better than on a 450 or 707 (not difficult in the latter case). However legroom in the bay seats is as poor as on a 707, but the very substantial table partly makes up for this. Shame no seat back tables on the airline seats.

An Irritation is that the charging sockets are underneath the front of the seats rather than the rear of the seats in front.

The three vertical grab poles around the doorway don't look like they'll interfere with boarding and alighting as was suggested they might. There's plenty of space around them. Whether they just encourage standing there rather than in the middle of the coach remains to be seen.

Heating just right and ride quality typical Aventra, ie not as good as a 450 or 458, but acceptable for a suburban train.

PIS pretty much bog standard Aventra, and it of course coped with not calling at Sunnymedes.

Acceleration didn't feel quite as good as a 707, but better than anything else on SWR.

The guard was not involved in despatch except at Datchet towards Windsor when the driver requested degraded despatch.

Plenty of uniformed and non-uniformed staff on the train.

I don't like using the T word, but these really are going to be transformational when they start entering service in volume.

It makes it all the more the pity that they have been so delayed and, poignantly, are very possibly going to be the last trains designed and built at Derby.

I've just seen a photo that shows that they do have the same 2cm middle spacer as the 700, just not the sidewall one.



The frames are, the cushions aren't (as per Northern).
Here's a photo I took this morning showing the spacer and how the bulkier cushions take up the space between the seats.

Nice train, possibly agree with the window seats feeling cramped but generally no worse than other trains. Very chatty guard made it even more enjoyable. What was the 701 sat at platform 18 not in service when we arrived at Waterloo?

The grey panelling really dosent go well with the brand makes the train feel dull and gloomy inside, should’ve really had more light blue panneling like every other fleet on SWR has.

But hey ho, thats my opinion on the interior. Most people probably wont care or notice

I’m actually a fan of the silvery look Aventras have inside, I think it makes the train look a lot less dull than Desiro City.

701 looks nothing like the other Aventras, externally. Much different profile to the rest. Maybe the 730 is the closest at a very very big stretch of imagination.

Well, none seem to have broken down in service yet, so that's a good sign.
Well, to be honest one round trip per day (that's more or less empty) isn't really a true test, if it can stay in service for a whole day's diagram that includes crush loaded services then I'll be more impressed

That's the thing with the Aventra. Every one is different.

The only other one with 20m coaches is the 710, so in some ways it's probably most similar to that, but certainly not internally!

If they don't break down when they initially enter service that'll be a first for any new train!

I'm sure there will be problems at first (what a debacle the 458 introduction was!), but undoubtedly Wimbledon will work its magic on them.

That's still the CET point for 444/450/458.
There's also the CET on 3 Top Yard, but probably not enough room for those new cabinets up against the shed wall?
From talking to Vogelsang a couple of years ago, the full clear out of the waste post reactor treatment takes about 3-4 hours.
Are 701 037 and 701 039 the only two approved for use on this - or could the remaining two days produce a third unit?

Not that it helps me much as I'm in the office... but I'd just like to know...
There might be a couple of other contenders. Whether they come out to play or not I don't know.

To be honest, with 4-5 years of delays that is quite a lot of time to iron out most of the Kinks. Sure nothing can fully prepare you for full load rush hour service running but most of the software and technical issues that have plagued the likes of the 345s Id expect to be much less in the 701.

Will see about Thursday and Friday?
BBC News update
Stuart Meek, SWR's chief operating officer, said: "We're very keen to get the full fleet into service as soon as possible, but we need to do that cautiously."
He added that the trains had to "meet the standard in terms of customer service, safety and reliability", and that "the last thing we want to do is put a train into service and for it to break down on the tracks"
Mr Meek described Tuesday's journey as the "next step on the journey" to introducing the Arterio into full service.

the 5Q50/1/2 tests from Eastleigh were cancelled today, presume will resume later?

Class 345 doesn't use the same software as later Aventras. Class 345 uses a derivative of Electrostar software whereas later Aventras, starting with class 710 use the software platform designed for Aventra.

MITRAC, it's called. I don't know what the Aventra software is called, but the bodging of MITRAC was why the 345s were delayed, which in turn was why the 710s were delayed (cos the needed a watertight brand-new software system).
Mitrac is Bombardier's traction system. Its software does not have any external name but can be split into early Windows-based Electrostar (357s, 375s, 376s, all 377s, and 387s), late Linux-based Electrostar (379s, 345s), and Aventra.

So is the Aventra software not based on either Windows or Linux?

Indeed, and I do know from a contact that the 345s are still having a lot of problems. But they still manage to run an intensive, very busy service day in, day out. Except when infrastructure on the west side fall apart.

I was on the run on Tuesday and one of the SWR management (I can't remember who) said they had 2 or 3 units ready to run, so there could be a third unit out this week

Iron out the Kinks, Waterloo Sunset?
