Scotrail HSTs - 4-5 years in

Isn’t there a real risk point in the latter part of this decade when presumably 50+ year old stock will further degrade in performance and other options such as single DMUs will also be approaching end of life ?

No.

The HST sets are mechanically the youngest units in the fleet. The power cars in particular were rebuilt with the MTU mods around 2005. The modular design of DMUs means they also cycle out mechanical components on a very regular basis, so you're only really talking about an aged body shell - and this can be patched (or run round with visible corrosion holes in it, depending on the will of the operator...). I suspect (though, no doubt others can confirm) that the main HST issues stem from a refurbishment/door project that was specified and budgeted as a short term solution, rather than a major investment.

Would seem a high possibility of a perfect storm.

Pretty unlikely. Actually, in most cases the opposite is true. Look at the issues at TfW and WMT (and by extension, EMR), where the fleet plan is based on wholesale replacement and introduction of a new fleet. Teething issues are far more likely to throw an almighty spanner in the works. The question with the HSTs, for me anyway, is are the current problems essentially on-going teething issues?

Is there another train fleet of any age which, over 4 years after the first train was in revenue service (15/10/18) has a fleet availability close to the 48% achieved on Tuesday ?

When the other HST operators (MML, East Coast, XC, Grand Central, NR) did it, the payback was through increased time between bogie overhauls. In some cases the increase was from 488,000 miles to over 600,000 miles between overhauls. Why GWR and ScotRail both decided against is a complete mystery.
Personally to me it makes sense as the lathe can be used on multiple different types of trains and provides a increase in ability and capacity, where as fitting the newer WSP only benifits the HSTs

Say what? So you would not fit upgraded WSP to the HSTs even though it reduces long-term maintenance costs and means you have more trains in service than sat waiting for the lathe. You do realise that the objective is to have trains in service earning revenue, don’t you?

Yes but the cost benifit analysis comes in to it and the HST are not here for the long term so why invest in the actual trains when a slightly higher investment gets you a longer term benefit

They appear to be under the impression that it's a choice of fit WSP or have the wheel lathe.

Even with the best modern WSP equipment in the world, you'd still want a lathe or several...
But the difference is your turning changes from unplanned, for flats and cavities, to planned, wear. Much easier to plan and deliver one than the other and consequently not impact upon vehicle availability.

Yes, but you’d rather have sets in service than stood down for an unscheduled visit to the lathe.

Of course and that's why the two in combination is the ideal option.

I was replying more to the suggestion that you only want one or the other and not both.

How are you defining "long term"? The HSTs are on lease until 2030.

With GWR now announcing that they will withdraw their HSTs in a year, perhaps ASLEF will now put more pressure on ScotRail to do the same. DMUs will be thin on the ground for lease after this date.

How easily can MK3-HST coaches be modified to run with locomotives other than class 43s?
GWR don't seem to want to, but are being forced to by the Dft to save money (and presumably cut services or service lengths somewhere unless something else is arriving from somewhere)

Having done cost benifit analysis in my previous work , your planning 20 to 30 years down line , if not longer i.e. floor fridges your planning 20 years , cold room 30 years .

None of which is relevant to fitting new WSP equipment to HSTs! It is quite a quick payback as it extends bogie life: the ability to get from 488,000 miles to over 600,000 miles as a result is a significant saving.

RTT will do that for you! ;)

If anyone wasn't aware, you can just type headcodes into the general search bar and it will find the service(s) to which they apply.

Alternatively, from December, ScotRail's own timetables show which services are booked 17C.

You can also seem them at the link below.


Whether that page is kept up-to-date is another matter!

Interesting, I hadn't realised that existed!

Looks up to date to me.

New announcement recordings seem to have been rolled out.

"If you see something that doesn't look right" announcement has been re-recorded in a different tone and a much slower pace. "See it, say it, sorted" also added to the end of it - as well as an additional announcement for "validating smartcards before boarding".

Does it improve acceleration and braking.

It improves them in the sense that it makes much better use of the available adhesion. It also improves the ride for passengers: there's much reduced coupler snatching as the WSP backs off the power and re-applies it (the original system was, shall we say, fairly agricultural in that regard).

Neville Hill had it down to a fine art: it was rare to experience a wheelflat, even during leaf-fall season, on their fleet.

It improves the ability to use higher braking steps without fear of inducing a prolonged slide; I experienced slide activity at low speed entering Perth Station in Mid-October. We stopped fine, but I could feel the WSP working and we came to a hard stop - the brake was no eased and in fact I felt may have been increased a step shortly before we stopped. We also had a less significant spot of WSP activity entering Pitlochry but at higher speed, for less time and the brake was eased this time.

I understand the FGW 'Step 3' max instructions were derived in part from the lack of improved WSP.
