Looking at doing a trip on the line and hope to do it on HST, thanks.

How many sets are actually in service per day?
It is still variable, but I do feel it has improved in the last two months.

There have been 15 out several days recently.

Last 7 days:
Fri 28/04 - 15/15 (one part failure replaced by 170 on 1T84/1H21 and later fixed)

Sat 29/04 - 16/15 (one part failure (Safety systems) 1T88 at Perth)

Sun 30/04 - 13/13

Mon 01/05 - 15/15 (HA11 failed on depot)

Tues 02/05 - 14/15 (HA13 failed Edinburgh before diagram)

Wed 03/05 - 13/15 (three failures, HA01 failed mid-diagram; HA04 on depot & fixed for 1H29; HA05 failed on depot)

Thu 04/05 - 15/15

Many thanks for the detailed response, which route is the most common for them?

I'm sure GWR's little fleet of HSTs is a reliable one. I'm sure GWR's big fleet from pre-IEP, which included all of the HSTs we're discussing here, was a reliable one. And I'm pretty sure XC, LNER/VTEC, EMT, etc. had good HST reliability too. What has ScotRail done with them that's gone so wrong?

You don’t think that Laira, SPM, Neville Hill and Craigentinny having maintained HSTs for 40 years or more compared with Haymarket having never seen them before (and not seeing diesel-electrics for 30 years) might have something to do with it?

Always a possibility that they don't know? Alternatively too much interference from Transport Scotland...
From what I've been told previously, a lot of the time it's niggly little things...

Well I do now, thanks. That said, I'm sure you could have told me rather than wording it sarcastically.

That's pretty decent. Hope they keep it up.
Do wish they'd have a couple of Spare sets to step up when required instead of the Class 158 substitution!

I think this is fair. There are more sets around and if your train is diagrammed for a HST then it's much more likely that is what will turn up.

There are still problems of course which is frustrating, because they are still very pleasant to travel on.

It's not really that decent considering we were set for 27 sets! (26 now due to the Stonehaven tragedy).

Do days with 15/15 scores mean that all booked sets have run successfully or do they include days when a "spare" set has been substituted in at the last minute?

If a set has failed/been subbed, I've put that in brackets. The figure is the number of sets out and which have worked at least part of a diagram.

Ie a set failed on depot wouldn't count to the total, nor would a set which failed before working the first service of a diagram.

So it's essentially sets that have worked at least one passenger service on that day

Thanks. So the "spares" are actually being used when possible. If there are six of them I'm guessing it's something roughly like a couple of them on hand at Glasgow and Edinburgh and one at Aberdeen & Inverness.

I don't know about 'spares' per se, what there is are six sets more than there are diagrams.

There's not a lot of space around the country to have spares hanging around just in case especially with the lack of shore supplies to keep spares fairly ready to go,usually quicker and easier to pump out a 158.

Sod the poor passenger cramped on a commuter train instead of an Inter7City, eh?

Wow, so even with more than a third spare, a full (albeit limited) service is still not always attained? That's not the best
6 out of 21 is 2/7 (28.5%) rather than a third.

Even if there were 26 sets as originally intended, I believe the maximum planned number of diagrams was 21 so 5 sets would be spare or on maintenance.

Given the reliability is worse than anticipated, having a further set spare/on maintenance seems prudent enough.
