Also her tablet was misbehaving when connected to the onboard power socket. Typing or any screen press often wasn't where she pressed. It didn't happen when she took the cable out. I didn't have an explanation of what might be the cause of that

I've heard stories of disruptive equipment as well. I think the logic is when an IET is travelling on AC power, it appears to interfere with some devices that are plugged in. I'm led to believe it doesn't happen when switched to diesel power and suggests it has something to do with an interfering frequency from being on the overhead wires that is being picked up by the charging cable.

Two more trips as a passenger for me today. Didcot to Paddington and back.  Both 10 cars as booked, air-con working fine, seats plentiful, acceleration and general performance far superior to a HST, the sun blind most welcome on the return in the evening sunshine, and (most unexpected of all) a ticket check in both directions!  No trolley seen on either service though.

Though of course, Iím just an apologist for the new trains...  Wink

Yes, IMHO you are an apologist for the new trains, this is no more a personnel insult than I feel insulted if called a critic of the new trains. Both are factual observations.

Full length IETS are undoubtedly an improvement over half length ones, and the full length ones are an improvement in capacity if compared to an HST.
They still do not feel like proper intercity trains, and despite some favourable reports, are still generally considered to be a downgrade.

I donít mind being described as an apologist Broadgage, and certainly donít take it as an insult.  I know in my own mind what I am, which is somebody who strives to be objective, balanced in opinion, open to change, and quite prepared to criticise whenever I feel it is justified as well as give praise.

Sadly, thereís certainly been more criticism from me than praise so far in 2018.

Cross posted from the May/December 2018 timetable thread as its relevant here as well...

There is no doubt this has bought Network Rail extra time to get the infrastructure works completed but no one will talk about how late they are running with these just that its better to delay the introduction of the new timetable.
Think this confirms my thoughts above:

Modern Railways Roger Ford on Twitter:

Electrification to Cardiff has been delayed to June/July 2019.

So donít be surprised if the May 19 timetable change comes and goes with no major timetable change on the GW network.

A quote on the WNXX Forum yesterday (11/07/2018) from a GWR employee:
Quote
Mark Hopwood informed us this afternoon that electrification through to Cardiff has been put back, possibly to June/July 2019. The IET and 802 delivery plan will stay on schedule with considerably more diesel mileage than planned.

...so expect many announcements ".....train service has been cancelled due to shortage of fuel." Tongue

Iím not convinced that the marriage of long trains with short platforms really works. I was on the 18.42 from Paddington which is 12 carriages. I was in coach 7 which is the last to platform at Slough (its first stop).
I counted 240 passengers emerging from coaches 8-12 once it was platformed. 240!!

It was platformed for nearly 5 minutes to do this. How does that fit into the timetable?

And then it shut its doors and proceeded, leaving 50+ still on the train who hadnít made it through in time. They are not pleased.

I didn't realise IET trains could be in 12 coach formations.  How does that work when the sets are 5 car or 9 car fixed set formations..... Roll Eyes Tongue

They can't be. 5, 9 or 10 only.  1842 booked for Cl 387 where passengers can walk through the train before Slough.  They will have to learn to listen to announcements.

Seems to have had an extended stop at Slough every day this week.

As I mentioned in the 387 thread a few weeks back, all it takes is for a few people to stop by the rear door of coach 8 (coach 7 for Slough) and that backs everyone else up who have no choice but to walk through once already platformed.

Or has been the case when I've been on these trains they're so crowded from cancellations and short formed stock elsewhere that you can't move forward. People are standing in all the coaches so you have no choice but to stand in one of the rear end coaches and hope you can get off in time.

Lucky you weren't on the 1751 (1D93), that stopped at Reading for its nightly lets waste 10 minutes trying to workout how to disconnect 4 carriages for absolutely no reason, only for us to be told that someone had pulled the emergency stop, and then finally 30 minutes after we had pulled in, that the train was going no where as it was all locked up and they had no clue what to do! The guy I spoke to had to manually open all the doors to get us all off and said he had never seen anything like it before!

Anyone know what the actual problem was?

Apologies, I'm not great with train numbers and designations - I'd only just understood turbos vs HSTs.  If this is in the wrong thread then I am sorry.
It was a 12 car new shiny train, and my point was really about the long dwell times and that passengers got stuck on the train, facing at least a 30min return trip from the next station, once the driver lost patience with disembarking them, shut the doors and drove off.

I wouldn't worry about the stuff in little text.    There is a problem with stopping trains that are Y carriages long in stations which can only take a maximum of X carriages, where X<Y, unless Z (the number of passengers getting on and off) is a small number and W (the time taken between stations) is long enough for a train manage to walk through in "Collie mode" - i.e. gathering passengers wishing to leave the train ahead of himself.

Works well enough at Dilton Marsh and Avoncliff.   Was failing at Melksham because Z was an increasingly large number.

What is going on with the platform extensions at Slough and elsewhere?

Network Rail's project W004 (Thames Valley Electric Multiple Unit Capability Works) includes stretching all four through platforms at Slough (and 9 others too) to 12-car length. It also covers any other NR work needed for 12-car trains to run and to call there. It was due to complete December 2017, and in March the milestone "EIS Infrastructure authorised (Paddington to Didcot) - Infrastructure authorised for passenger use" was listed as completed.

So have they actually done the work, or is that just not true? And if it is true, why don't the trains use that length? The only other step I can think of that's needed is to tell the trains to stop SDOing, and surely that doesn't take several months - even for GWR - does it? Note that work on SDO balises was excluded from W004, but for NR to not do what the trains need, or for NR and GWR do be still arguing about what that is, would be equally inexcusable.

PS: yes, this strand does belong on the thread about 387s, where earlier similar discussions took place.
