I went on a couple when they first launched. nice to ride on.Do the TPE mk5s knock in the same way, because if they do then I don't want them in England now and again, and I certainly won't want them in Scotland on a daily basis?

You mean like Hitachi and Siemens to name just two who have a contract to provide a set number of units per day in return they are responsible for maintaining the fleet so is rather important to them to ensure the fleet is reliable.Looking from the outside in, it does seem strange how there appears to be three (?) sets out daily performing reasonably well recently (to me at least, granted I don't pay that much attention). It seems to suggest that at least some combination of loco & stock operate without a hitch. If interface issues are what's holding them back I suppose they may be keeping those combinations together for as long as their exam cycles allow (I believe the stock & loco exams don't align to allow this), to eliminate any 'problem' loco / set combos?
I don't think failures such as the one you mention should be too much concern, if they're irregular. Those issues at this stage can be a part of a learning curve for the technicians, performance engineers etc to iron out over time. If those defects become regular then that's when quick action and a solid plan is required so they don't become too much of a burden on performance.
My own ponder is - would the entire situation differ if the contract was different. Ie. If the manufacturer was also responsible for the maintenance & daily availability, rather than the combination of TOC (TPE), the motive power provider (DRS), the owner (Beacon), the manufacturer (CAF) and the maintainer (Alstom). There must be lots of accountants between them trying to offset any penalties!
I also can't see them 'scrapping' the entire project either. More likely a solution will be found.
Many thanks for your reply, interesting to get an engineering perspective on things.Looking from the outside in, it does seem strange how there appears to be three (?) sets out daily performing reasonably well recently (to me at least, granted I don't pay that much attention).

I think some of the problems have been loco specific and not actually related to the stock. 68026 has recently returned to the route following extensive extensive repair work and has had problems three times that were unrelated in any way to the Mk5a stock.
I’m not sure if you’ve seen the actual TPE specific connector between the loco and stock, but the whole assembly and housing doesn’t look particularly robust. I wouldn’t trust such a delicate piece of kit in a nice dry office, let alone exposed to the elements over the Pennines! Again, if this is a problem then I’d guess an engineering solution wouldn’t be such a difficult thing to switch.
I think the significant improvement in reliability of the CAF built Nova 2 trains does give cause for optimism with the Nova 3 sets.

Only yesterday a York to Scarborough was 3-car instead of 5. Another was 3-car rather than 6 but they might have just detached the second 185 after the first shuttle due to lack of demand.
The Fyra EMUs mentioned previously came from AnsaldoBreda as they provided the lowest price...
Again, many thanks for taking the time to give an engineering perspective. I see your point about the pins, they are well back!I do know the connector you mean - they're made by Harting and are widely used on rolling stock. They're actually good connectors in my opinion but I'm not sure they're best suited for the environment they're mounted on, or for a circuit that is regularly disturbed, especially when careful precision won't always be a priority when going between rail vehicles! However, I think you'd do well to damage the pins & sockets as they contact only when the housings are aligned, just look at how set back they are in relation to their respective housings / bushings.
The detritus inside the connector of this photo shows they're not immune from weather ingress though, which could be a problem especially on those sensitive communication lines...

On the vehicles I work on they're used as a semi-permanent connector, so you only disturb them if you're either changing a component or fault finding (you would try avoid disconnecting and find a terminal rail somewhere!) etc. Most of them are secured by screws, rather than the clips too.
That was due to 68026 on 06:54 Liverpool to Scarborough being terminated at Manchester Victoria, with the problem being with the locomotive.Only yesterday a York to Scarborough was 3-car instead of 5. Another was 3-car rather than 6 but they might have just detached the second 185 after the first shuttle due to lack of demand.
Really? Given I was on a service stuck between Marsden and Huddersfield last summer during disruption at Dewsbury as platform 4&8 both had TPE trains in with drivers who didn't sign that route, I'm going to respectfully disagree.Most drivers and conductors already sign said route. Even Sheffield drivers sign part of it (Huddersfield to Wakefield) as one of the Manchester stoppers comes to/from Crofton depot allowing for fleet rotation and maintenance.
Originally there was the plan for the Manchester to Huddersfield stopper to continue to Wakefield Kirkgate (presumably part-replacing Northerns Castleford service), largely to free up Platform 4 at Huddersfield for LNER Huddersfield to Kings Cross services. However due to Covid neither has happened.

You can respectfully disagree but it’s true. I sign it myself as I had the joy of learning part of the route on Northern’s 3 times a day Hud- CFD route earlier this year. I believe videos of said route are also available on Don Coffey’s YouTube channel which show former driver refresh duties.
Manchester and York conductors and drivers both sign the route, and I believe that the Airport do too. I’m not too sure about Liverpool or Hull.
You have to remember however that very few night services operate that way (those that do are largely YK depot based). If a driver or conductor isn’t happy with their own competency having not been that way for a long period of time, they can refuse to accept the diversion of offered on the grounds they require a route refresh.
You'd probably need a substantial rewrite of the TMS on both the loco and the sets, as it is designed for one loco to be attached to one rake of five coaches. That is quite apart from any physical alterations needed.A rather left-field, theoretical question. What would be involved in sandwiching a Class 68 between two sets of Mk5s? Bit like an APT or 755.
You would have two separate 'trains' but not dissimilar to coupled Voyagers, IETs et cetera. Mk5 carriages are supposed to be quite short.
Obviously this will seem ridiculous to some. But. I think the 68 is too overpowered for a single rake of Mk5s. And everyone is saying the Mk5s should be binned from the TPE network.
Not quite everyone!. And everyone is saying the Mk5s should be binned from the TPE network.
Not quite everyone!
Some of us are hoping to enjoy them for many years to come.
I would be very happy to travel in First. A nicer seat and free cuppa would be good but the main attraction would be a better vantage point for the thrash.In 1st I assume? Nothing looks enjoyable about Standard bar the colour scheme. Decent seats? Nope. Window view? Nope.
What is the thrash?
Except by residents of Scarborough living adjacent to the new depotNoise of a diesel engine working hard. Some locos have better thrash than others. Class 68s are well thought of in this regard.

Happy New Year to you too!True. Let's face it, loco haulage in 2020 isn't a great idea.
Noise of a diesel engine working hard. Some locos have better thrash than others. Class 68s are well thought of in this regard.
So, just like petrol heads, hearing someone rave about ‘thrash’ is like witnessing anyone on top gear get too excited by the sound of a car engine being revved?

Sounds like this is getting closer...
What is, ditching them? Can you say more about what you've heard and where from?
Glad I got a ride; even though Standard is mediocre, 1st is lovely. Even beats the UK "king of 1st" the Pendolino.
)Thanks. I hope if they do they don't return to the land of short-formations again, but instead keep the 185s and reduce services so they can stick with everything being 5 or 6-car. Perhaps those local services that are a poor fit could return to Northern to release the 185s?
