One possibility is that before the GOP panel was fitted the water would not have been seen running down behind a wall panel. So maybe the leak is long standing. After fitment there is new access to view a hidden area.

Doesn't exactly inspire confidence given that IIRC many (all?) units had to go back to the factory for rectification after delivery.
It doesn't surprise me that issues are being discovered as the miles are (slowly) being accumulated. Likely more things will come to light especially as years in storage won't have done them (the 701s) any favours.

I can remember that in my car if the scuttle drain (leading down from the water collection area at the foot of the windscreen) got blocked the water would build up and find its way in through the ventilation fan !. The scuttle drain just lead to the void between the inner and outer wings. The water sometimes came into the cabin via the forward door pillar if the door seal was not quite sealing properly !.
So it might be an expected water exit route that is now occupied by electronics. After all water is good at finding its way into things especially when helped by gravity and lack of use. But being 701s nothing would surprise me !.

Please don't tell me that someone found a conveniently located hole when doing the modifications and decided to use it to run the wires through...?
I thought the GOPs were installed at the time of construction? AIUI all new build trains have to be built to be both DOO and conventionally dispatched so they were always planned to 2 GOPs. Even the TL 700s have GOPs and I very much doubt they’ll see guard dispatch.

If that is the case then it would seem to be either a build problem, or slightly more worryingly, a design issue?
AFAIK, although I haven't paid as much attention to them, none of the other Aventra fleets have reported water ingress at the GOPs so this problem appears to be 701 specific.
When I watched BBC ‘Inside the Factory’ on the 345 build, each carriage when assembled when through a sort of ‘car wash’ style piece of equipment where it was soaked in water for a period of time, this was to check for water ingress, I would assume all other builds at Derby would go through the same process?

I wonder if this wasn't as thorough after the resumption of work following Covid shutdown in 2020?

Old and new at Reading today.
Image shows 701 046 in platform 6, having arrived on a test run, while 455 860 is in platform 5, forming the rear unit of the 11:09 to Waterloo.

Does anyone know if 701039 is the unit named Ace, representing Tennis?
This one is 701034. Just seen it.

Was wondering between it and 701044 which was out too when I was passing. Thanks
If anyone sees unit 701039 can you confirm if its been named. I'm sure in thread maybe I've missed this(I know this is unimportant for some
).Just saw 701039. It says “Ace” next to the Arterio logo at the end.Was wondering between it and 701044 which was out too when I was passing. Thanks

There really is no limit to the depths of naffness that SWR will go to, is there?
The lack of self-awareness (on top of the multitude of issues with the introduction) is absolutely astonishing.

Yes. It's one of the names units were given at the Re Re launch in November -you know, the one that promised two more diagrams in February.
You missed one. It was actually the re re re relaunch
Isn't "re re re re relaunch" the noise made by a compressor on a class 455?You missed one. It was actually the re re re relaunch

Class 701 SWR introduction delays: what should happen now?
Moderator note: Split from https://www.railforums.co.uk/threads/class-701-aventra-trains-for-south-western-railway.148717/page-414#post-7170485 Three months to go until The DFT fully nationalise SWR and the ongoing TFL transition for certain suburban services. Hopefully there are plans afoot...

A recent SWR tag line for the 701 was "Your commute just got better" which amusingly they virtually stole from my small "computer" business in Worcester Park. I have been using it since 2004. Hopefully I have put a stop to them using it again.
It will be more of a shock now if we actually see a new unit in the rotation.
Guess those February diagrams are incredibly unlikely if there is still no variation outside of 6 regular units?

They've all worked every day this week so far - which is a first, I think.

Unless sarcasm, good luck with that!

Given how they can get 6 units out fairly regularly what is preventing other units from being ready for service?
