1c94 yesterday would suggest otherwise. 26 late passing Bedwyn on realtime trains, and on time at Penzance. Given a decent run (does occasionally happen), there is plenty of scope to make up time, it's just it is very rare for control / signallers to be proactive enough to hold a stopper for a couple of minutes here or there. By the looks of it, 1c94 yesterday was able to make up so much time as it was allowed to pass stopper 1c93 in the platform at Newbury which made a huge difference. Controllers and signallers should be given the freedom to be affecting descions like this more often.
And the 20 minute booked dwell at Plymouth.
If anything the Bedwyn Turbo and freight could potentially be altered to allow the xx35 to leave slightly earlier, where there is a will there is a way!
Bedwyn turbo maybe, however freight is by far more difficult, if a freight has firm rights there isn't much you can do if changes will not allow you to meet them.

also change a freight in one place and it becomes a clash somewhere else

True , but the B and H stone trains are reasonably self contained. I'm sure something could be done.

OK, well let's look at it from Bedwyn to Plymouth ARRIVAL (so no recovery time), 26 late passing Bedwyn, down to 12 late arriving Plymouth. That's 14 minutes saved, not bad. Also, if 1C93 hadn't been held at Newbury then 1c94 would have followed it throughout and been at least 40 odd late into Plymouth. So a very good decision by either the controller or signaller that decided 1c94 should overtake.

14 minutes is very good, however nearly all of it was down to allowances, SRTs which are inflated (which is not the norm), and faster than booked dwell times. So it isn't that impressive, nor what I would describe as being able to "make up" time in the way I think was being suggested. Yes for that particular train it was able to, but only because of its own specific circumstances. Although as you rightfully mention it is an example of good regulation, something you don't see much of anymore unfortunately.

Having travelled on the train as a passenger for part of its journey, I would slightly dispute your assertion that it wasn't down to driving performance. I can atest to the fact there was some very hard driving and quick station approaches.
However I very much agree with your second point, good regulation was very common years ago, but seems to be slowly dying out, presumably at Network rails behest?

Am only going on the data on RTT, although it is certainly possible that quick station approaches could have helped with those station dwell times (something RTT won't nessessarly give a true impression of).
I think the size of some of the workstations these days combined with the lack of proper training to signallers on how to actually regulate certainly don't help matters. The trouble is often delays caused by poor regulation typically get covered up by another incident, or are subthreshold so don't get investigated. Therefore the majority of the time no lessons are learnt.

100 percent this is my experience as a driver.

Seems it was specifically held back, perhaps to avoid blocking a platform at New Street, but that is pure speculation.

Ironically it was held up waiting for its attaching portion which seemed to be delayed due to a delay on the inward working of the stopper, due to a fire alarm apparently.
Unfortunately, the trains frequently trip over each other on this route. As mentioned above, if the stopper goes up late, it comes back late when then delays the down TfW train and so the cycle continues. It should get better in June when the WMT run the opposite half hour to TfW.

The 1230 is one of the few remaining hours where a unit detaches off the down and then immediately attaches to the up. The up train could run on time without the attachment but that might cause over crowding. I have no idea how busy that train is.

Given a decent run (does occasionally happen), there is plenty of scope to make up time, it's just it is very rare for control / signallers to be proactive enough to hold a stopper for a couple of minutes here or there.
Back in HST days, I had a few one hour, 53 minute runs from Cardiff to Paddington, about 10 minutes faster than scheduled. Coincidentally, that is the same as the standard schedule now with an IET.

Having worked many services to Birmingham from Shrewsbury for TFW, it is something that happens when TFW are running late.
The platform staff are there are very good and in direct contact with the Severn bridge junction signaller via radio.
I have seen the WMT get held a ridiculous amount of time as it was expected the TFW would only cause WMT a few mins delay, and I’ve seen WMT leave on time when TFW are expected to be heavily delayed but end up ready just as the WMT train leaves.

To add, once the route is set by the signaller, taking it back isn’t as simple as taking it away. They have to get speak with the driver and pretty much get their permission to do so.
Agreed. Generally regulation at Shrewsbury is good, there is a regulation statement in place, the odd misjudgement is made.

Should be better from June anyway with the departures to Birmingham more spread out.

Manchester Oxford Road to Liverpool Lime Street via the CLC is bad for this too, if the express is delayed by a few minutes, signalers will let the stopper go first even if the express has just arrived at the platform at Oxford Road, signalers then route the stopper into the Glazebrook loop to allow the express to overtake

One person's poor regulation is another's good; In the OP example, passengers on the Shrewsbury starter, and joining en route, would have been pleased their train was on time, whereas those on the further delayed Holyhead train were no doubt disgruntled. The key factor should be minimising overall delay and therefore disadvantaging the least number of passengers. But it is, as I said earlier, an inexact science, and when Train A is delayed by Train B, Train A's passengers, crew, and quite often different TOC from Train B, will inevitably not be pleased. In NR Control we used to reckon that if we got a similar number of regulating complaints from all our TOCs, we were being as fair as we could to everyone!

The TfW service lost 11 minutes following the stopper between Shrewsbury and Wolverhampton, but was then held at Wolverhampton for 23mins for some reason . So can we really blame its curtailment at Birmingham New Street on following the stopper?

Tis a regular thing now holding TfW at Wolves so they can be turned back right (*) time at Birmingham.

I would say the issues with prioritising trains are a serious problem in the WM area and the nonsense unworkable timetables (Inc Shrewsbury stopper turnaround time) need to go asap. Service should extend somewhere, both at the south end beyond New St AND the north end (Wrexham, Chester?) of the route.

* nothing is right time out of New St

Extending north end won’t happen. Shrewsbury - Wrexham Chester is already near capacity due to the crazy long signalling sections Shrewsbury - Wrexham and then the single line between Wrexham and Chester. If that gets sorted then it’s much more likely that liverpool-Chester would get extended through to Cardiff than WMT getting any of the paths. To add to this, WMT would then need to go through crew training which is expensive.

People have suggested it gets extended to Crewe before and runs an hourly Crewe stopper instead of TFW’s every other hour stopper. There were good reasons put forward again as to why that would be highly unlikely to happen.

As for south I’m not so sure what could be done there. It uses the bay platform at Newstreet though so shouldn’t be a huge issue.

The stopper only has a 5 minute turn around at New Street so getting that out late from Shrewsbury could have an impact on its return

To be honest that sounds a bit tight in a busy station such as New Street!

The days when trains could "make up time" are long gone. Speed is strictly controlled so any late running pretty much stay that way.
That in itself is indicative of poor decision making - there should always be a contingency reserve.

It appears to have been on time all the way to Gobowen, getting held outside Shrewsbury for two carriages to join to from the late running 11:08 Birmingham International to Holyhead. That train was delayed by a WMR Walsall - Wolves stopper…
This is precisely the sort of case I point to when someone suggests using portion-working rather than using proper length trains. It may save a few pennies to tailor the length of the train to precisely the number of passengers onboard, but it creates extra potential for disruption.

There is a place for portion working, but that place is Machynlleth, Crianlarich, or Georgemas Junction (a thing of the past in the case of the latter). Regular uncoupling on busier routes is asking for trouble.

Not that 1I14 can be considered "unbusy" between Holyhead and Shrewsbury. A couple of years ago it was the most frequently overcrowded train TfW had.

Portion working isn’t always for tailoring train length, though. It may be the only viable way of getting a through service to more than one destination when only one path is available in a congested area.

That doesn't apply in this case though.

Standard value is 4 and New St doesn't have a specific value any greater.
Even still, there must be a high chance of delays at a complex station like New Street so it would make sense for a reliability point of view to make it longer. For example, is there another route it could interwork with which would provide a more robust (say) 20 min turnaround?

At London terminals you'll rarely get 5 min turnarounds: the philosophy at London appears to be that interworking is preferable to tight turnarounds.

There is however it isn't designed to allow for making up small delays on every section of line.

This changes in the June timetable with longer turnarounds at New Street with shorter turnarounds at Shrewsbury. Issue with interworking is you risk spreading delay to route otherwise unaffected by an incident. The 35 minute turnaround at Shrewsbury I suspect more than makes up for the 5 minute turnaround at New Street.

You run out of platforms very quickly at New St if you do that. As the West Mids is widely electrified, what are you going to interwork with? Hereford?

The 1240 WMT Shrewsbury to Birmingham NS was allowed out before the delayed 1234 Holyhead to Birmingham International even though the latter could easily have got away at 1242. This is causing big consequential delays to the latter with missed connections and it is now terminating at New Street. Who prioritised the stopper and why?

The exact same thing happened with those services when I was last at Shrewsbury back around October. The previous WMT had been cancelled and the Holyhead was a few minutes late arriving, so there were a lot of people at Shrewsbury anxiously trying to work out which train was going to actually go out first and no-one seemed to know. I punted on the WMT and was 'lucky' that it did indeed go first, but I felt a little guilty about having told a confused lady it was probably best to take the ATW as she was going to Birmingham International, when as I found out later that it didn't actually get there and terminated short at BHM due to losing loads more time from being stuck behind the WMT.

It does seem to be badly planned to have only 6 minutes between these trains when the earlier one has come a very long way, *and* needs to attach carriages, *and* needs to go out first.

I most definitely wouldn't call it rare given the amount of stock that has been disposed of in certain regions (Southern for example)

That's true, I'd forgotten how little is still diesel at New Street these days.

My comment was based on various CWNs I have from 1981 to 2013 (plus 1967, though that is a long time ago) so admittedly it's based on pre-Covid times. In these, there's the occasional suburban with a 6-min turnaround but that seems to be the lowest.

Interworking is done a lot at London terminals though, so there appears to be no widespread view that it's bad practice. However I take @The Planner's point about lack of other diesel services - still instinctively had it in my head (without thinking properly) that Hednesford/Rugeley was diesel... shows what era I last spent much time at New Street I guess! ;)

Sometimes you have no choice, but avoiding it is not a bad thing. I don't think London Terminals are a fair comparison here, a good chunk of London termini are served by one main route. New Street is serving a number which diverge there so avoiding interworking serves more benefit here.

Think of New Street more like Brighton, where there is typically no interworking between each of the three sides (to Lewes, Hove and Preston Park). Interworking Hereford with Shrewsbury would leave you with a crossing movement in the throat, like you would at Brighton if Seaford trains ran through to Littlehampton.

I see what you mean, there is some sign of that at London terminals which you have 2 main routes (e.g. at Waterloo, interworking between the main and Windsor routes, while it exists it is somewhat limited).

Having had former colleagues working at Shrewsbury, this was a semi regular thing. The gambit was that indeed if the TFW was late the WMT stopper would be allowed out first but then the WMT would be lopOed at Wolverhampton by the TFW to get it back ahead of WMT. It sounds like on this occasion that this was the plan and then something else snagged the TFW service at Wolverhampton.
However often it would be the reversal - WMT stopper would be held regardless of upto ten mins awaiting the TFW to come through and leave first.

This kind of thing happens all the time on the Western. I've lost count of the amount of times I've been on a westbound fast, held at Fairwood Junction (Westbury), whilst the late running stopper is allowed to trickle out in front of us. I think it's a general unwillingness for signallers to make proactive decisions, partly, because I believe their hands are tied and they would need to get authority to do pretty much anything contrary to the easy option.
that's interesting because the only time i've experienced something similar to this the exact opposite occurred - specifically involving a late running Portsmouth-London train and a Haslemere stopper about a week ago. the Portsmouth service was running 18L by the time it reached Haslemere. Instead of putting the stopper in front of it they held it until after the express although it ended up running 10 minutes late in the process. The benefit to this though was that the Portsmouth service was able to skip intermediate stops between Haslemere and Guildford + Woking as the Haslemere service also stopped at all those stops.
