The mainline tests like 5Q51 1115 London Waterloo to Staines Up Loop on RTT have been cancelled this week, presumably all the physical modifications are complete and Alstom are waiting for a new software release update (after the 345 updates) to test on a test track, and then mainline?
Looks like yesterday on Realtime trains 5Q50/5Q51 (a 701?) ran a test from Eastleigh to Waterloo and return (updated software?).
And running again today.

It's not like car manufacturers don't have software issues. Look at all the issues VW Group have been having- various important new EVs have been delayed by software troubles with their 'Cariad' software subdivision. Software troubles affect a lot of companies.
Indeed so - my JLR Discovery Sport PHEV took 13 months from order to delivery, then has had software issues ever since. The more software, the more there is to go wrong - it's inescapable and begs the question; should software advancement not be followed doggedly by the railway, in order to improve reliability - in other words, lag a little behind the technology wave?

More software doesn't necessarily mean the more things there is to go wrong. It's how the software is implemented and also backed up by redundancies / fail safes that makes the different.

The problem these days is many manufacturers of vehicles, utilities etc are outsourcing work to places for cheaper labour and in these cases skimping out on what they can with these softwares to save costs of which the things they're attempting to go without would otherwise help to make the software reliable.

Add in that the time wasted and miscommunication of then trying to relay and solve issues that arise on software made outside of the general operating area / country means I'm the case for some like Bombardier the update rollouts take much longer and by the time one fix is ready then another issue may have popped up.

My parish council newsletter (Horsley on the Guildford via Cobham “New Line” ) says that the promised phasing-in of the new 701s on our line “will be well underway before the end of the year”.

Inside information? Or a too-optimistic guess based perhaps on out of date SWR press releases? What do people think?

I hate to regurgitate the old line... but did they state which year?

Have we ever had a TOC whose newly ordered fleet won't have entered service within the lifetime of the TOCs yet? Granted, SWR has 2 years to go and the 707s are close but they were ordered in the very later days of the SWT Franchise whereas these 701s were ordered in the early days of SWR... Back in 2017.

Weren’t the first batch of Southern’s Electrostar’s ordered by its predecessor Connex ?

No, I believe the first batch of 375s were delivered in 2000 to Connex South Eastern, well within their tenure. Connex did order some 375s for the South Central region (later redesignated as 377s under Govia), but the announcement was already made to not pursue Connex's franchise beyond 2003.

Following so many missed deadlines, I'll only believe they're entering service when I've seen one carrying passengers.

After all we've seen two "new" fleets in the locality failing to enter service at all. Admittedly the 442s and 769s were rebuilds not brand new, but the 769s in particular were always imminent, until suddenly they weren't ...

Yes 701053 today (13/06) was on 5Q50/5Q51
Thanks, on the real times website the tests seem to have gone well this week, doing a Google search on 701053 found a couple of youtube videos from this week
A sign mechanical and software issues are being sorted?

Ok thanks for details, my memory’s clearly faded .

The 707s had just one run in service with SWT. SWRs reinstated 442s are another close call.

Do GWRs 769s count?

What about LNERs 80x fleet?

043 was moved from Wimbledon Park to Farnham Sheds this evening (19th June), joining 035 which arrived on 9th June. There’s another Wimbledon to Farnham path shown on Real Time Trains for tomorrow night too, so possibly another 701 going the same way but that’s just an assumption.

5Q87 tomorrow: https://www.realtimetrains.co.uk/service/gb-nr:K03476/2023-06-20/detailed
029 was the performer on the Wimbledon Park to Farnham Sheds move today, so Farnham now holds 029, 035 and 043.

No update yet from Rock Rail, their accounts need to be filed latest by 30th June (end of next week). Looks like they are waiting until as late as possible as the notes and Directors report should give clarity

The part in bold is the problem. British engineering is usually not... err... up to par. ;)
But this isn't really true, or at least not uniformly. At least the Japanese seem able to come to the UK and make cars with Japanese quality, see the Toyota Corolla and Nissan Qashqai!

I've been told by SWR today that they are to be in service by the end of 2023. What does everyone think the likelihood of that is?

Looking forward to seeing one unit running one service - an extra, just to safe - late in the evening on 31 December 2023 :p
And due to delays it will run so late that it is actually all in the next day of the year..... Oh.

This reminds me of TPEs sterling efforts to run the push pull Mk3s as promised - once iirc ?.

Just like SWT did when they ran a single Class 707 in passenger service in the final week of their franchise? At least they can claim to have introduced them in their franchise...
