TPE Mark 5A coaching stock progress

[SP Man]

Would the wheel flats not be caused by the brake testing that was reported above?

Vorrect, Nothing to do with driving style. During this style of testing their are requirements to do either full service or emergency braking from 100 to 0. The test staff are well aware that testing in Autumn/winter raises the risk of flats. 1 coach as flats on all wheels which suggests a possible WSP fault on that coach as all other coaches have not. It is as stated just one of those things when the tests dictate that style of braking.

Have the driving trailers always had those buffers? It just looks diffrent to me

 

[SP Man]

Yes the CAF DTs built with the buffers, shackle and pipes.

[Shughes343]

Does anyone know if any runs are planned for tomorrow at all?

 

[Erniescooper]

Nothing happening tomorrow, should be some overnight running next week and set 6 arriving

 

[Bornin1980s]

Last night, I dreamed that the driving trailer was literally an insect, derived from some sort of translucent ladybird (it didn't make sense - real ladybirds are prettier).

 

[SP Man]

Swooping 68019 over with 68022 tomorrow. Get there about 1130 via Wilmslow and back about 1300. Next out on Wednesday night between Stafford and Warrington.

How far off are we from seeing the Mk5 + 68’s being tested over the North TPE route?

Just in time for HST replacement with ScotRail.

A couple of other forums and FB groups are reporting that Network Rail has put a temporary not to be used on all Mk5's. Not sure of the exact problem possibly to do with the bogies. Not heard anything myself and not 100% sure on the validity of this but thought it was worth posting.

If true... oh dear...

 

[mikemcniven]

This is NOT TRUE I thought at first it was, but people in the know have confirmed it's "Wibble"

 

[dilbertphil]

Glad to hear it. Thanks for confirming. Thought it was strange I'd heard nothing at work, but lots of internet chatter about it today.

I had seen the same too, even thought it true myself, but someone working on the introduction project of the NOVA 3 have said it's false, CAF, TPE, Freightliner haven't been told about any such "ban" and the next stock due to arrive tomorrow, hauled by ROG 57812, with a test run on Wednesday evening to Stafford with a run to Warrington BQ and back before returning to Longsight

Any updates in light of the Caledonian Sleeper announcement?

Any updates in light of the Caledonian Sleeper announcement?

I don't think the Sleeper announcement will have any immediate implications for TPE - the Sleeper stock is way more complex and has a whole load of different features and equipment, especially for interfacing with the loco. As far as I can tell, the TPE stock is somewhat more conventional, and is much simpler in the way it operates (fixed formation). Willing to be corrected on that, though.

 

[BMIFlyer]

The actual issue was on the CS stock when a handbrake turned itself on by itself whilst the train was in motion.

The TPE stock is NOT affected and testing is continuing.

Correct the TPE stock is pretty muck classed as a Multiple Unit due to its fixed formation.

It's kind of more like a 4-TC than LHCS, I suppose - an unpowered multiple unit.

Are the handbrakes manual or electronic?
If electronic, who thought that was a good idea?

I must admit I never understood why car manufacturers think having the "brake of last resort" as anything other than wholly manual is anything other than a really, really stupid idea.

Don't get me started on that, I've lost count of the number of times I've had huge stalls as VW don't trust me with an actual handbrake.
Anyway, I digress.

 

[SP Man]

If the handbrakes are like the Mk5As then it's a spring applied handbrake. It needs air pressure to hold it off and if it loses air pressure the spring will put the handbrake on.

Quite- the Southern region would have given them a 4xx number. Then again, I suspect they'd have done the same with the mark 3 and mark 4 + DVT sets.

Sorry for being thick / pedantic, but isn't a 'handbrake' by definition something that is applied by hand - ie manually as opposed to automatically?

 

[InOban]

Which is why they are commonly referred to as parking brakes.

In a car the term is synonymous with parking brake (which is probably what the manufacturers actually call it) - but on trains?

Both. We used to call it a handbrake on the 86 because of it being a traditional wheel. However the 87 had a hydraulic version and our current stuff is definitely called a parking brake now. Knowing the railway though, that same 86 brake would probably be called something different depending on what depot you worked at.

Sorry yes it's technically a parking brake. I'm a freight man so deal with handbrakes so just generally refer to it has a handbrake .

 

[Bornin1980s]

Do freight trains still have real handbrakes?
