Class 175 to GWR

[fgwrich]

You don’t clear physically any more. You have to get virtual clearance first. You input the specific vehicle class characteristics into the model and compare them with the infrastructure measurements. Comparable clearance, using other classes as a comparator, is not now allowed.

The model usually provides a list of close calls or exceedances, which you then work through with NR, location by location. Once you have done this, you get your Statement of Compatibility for the line concerned (with any speeds or prohibitions listed) and off you can run.

You still need to do physical runs to check signal sighting, passenger/train interface issues, etc.

Very much so. I remember when the first PTI clearance runs were conducted ahead of the prototype 150/0s joining the fleet (and something that I’m still proud to have taken part in). Basingstoke to Reading may have been well within clearance for 150s, but it was still necessary to send 150130 along the branch for a day, despite its 2 vs 3 car nature.

What I will say though, there’s a little irony in that Laira is starting to look a little more like Landore at the moment with all these 175s arriving into Lipson.

Any further news on entry into service timescales?

September has been mentioned. Before that is pretty much no chance.

Not even a whiff of dates for guard training yet and before us comes the drivers.

OT, but this explains why Class 379 is having to be cleared for operation into Kings Cross despite the 387s being well established.

Are the castles are staying beyond May? Realtime shows more diagrams, including two Sundays

Yes, the diagrams are on this forum somewhere. Also I think (again it's on this forum somewhere) that the timetables for the PNZ-EXD (formally PNZ-CDF 5 car IET) no longer shows a 1st class ticket, I assume so that a 175 can be dropped into the diagram.

 

[Wyrleybart]

Surely they could bring two units at a time. Also probably time for a gauging run round the Devon Metro and maybe Cornwall.

I think it might be a brakeforce issue. Might be wrong but I am reading between the lines that the class175s are not braked during their (hauled) transits, so the brake force comes from the locos and barrier vehicles. Technically, only a small numberof piped vehicles are allowed at a time. Prior to around 1981 it as five vehicles piped but at least five with operating brakes on the rear. That was subsequently changed to three and three. So you would need a vehicle with operating brakes between the 175 units.

Rules may have changed and ROG may have dispensation anyway.

Presumably the brake force of a 37 allows it to be counted as 'two vehicles'?

Do we know if this is still running and which unit is involved ? Thanks David

 

[TurboMan]

Should be 175007.

 

[windjabbers]

Should be 175007.

Thanks BW DC

 

[The_Train]

Could anybody kindly update me on the whereabouts of the following and roughly when they arrived at their current location please:

175008 - my last update was it being at Ilford in July 2023
175101 - my last update was it reaching March in Oct 2024 but I presume it has since moved on to Ely
175107 - I have no update of it leaving Landore for Ely
175116 - my last update was it reaching March in Oct 2024 but I presume it has since moved on to Ely

Thanks gang

 

[REVUpminster]

Hasn't left Ely yet. They have all left 3-4 hours late and arrive early at Laira. Why they have these timings I don't know? Maybe to do with overtime?

It has left under an hour late.

 

[JakeMurphy]

It’s having a funny run, got to Leicester making up it’s time, now being held there and it’s nearly back where it started…

 

[Class15]

It’s sitting on the goods line at Leicester station right now on Railcam Diagrams. 4M29 just overtaken it.

 

[TBaldwin996]

Railcam showing cancelled at Leicester and tucked into Leicester LIP at 15:08 due to the ‘wrong unit taken’. Incredible.

That’s ridiculous

 

[The_Train]

As hilarious as it is to think of someone picking up the wrong train, what does it actually matter as to what number unit is moved and when as GWR are taking them all anyway?

 

[D6975]

If the unit taken is one that still needs attention, then it makes a huge difference.

 

[The_Train]

They probably all need some level of attention considering how long they have been out of action for now

I do find that quite funny!

Apparently that is the case, needs to go back to Ely.

 

[The exile]

Someone’s going to have an interesting meeting!

That is the most incredible reason for a cancellation ever surely. What are they now going to do with it at Leicester? Railcam says ‘awaiting events’ - this could well be a problem if it can’t be fixed at Leicester! Wheelskates back to Ely?

By the way the unit that was taken was 175010, and it should have been 175007 (according to Railcam)

Let’s hope that what needs fixing is not bogie-related.

 

[brad465]

Brings a whole new meaning to "I've got the wrong train!"

 

[JakeMurphy]

Something to do with a known axle issue on 175010 apparently
