From The BBC» (British Broadcasting Corporation - home page)

A man has died following a low-speed collision involving two trains in Wales, British Transport Police (BTP (British Transport Police)) has confirmed.

A further 15 people have been taken to hospital with injuries not believed to be life-threatening or life-changing, the force said.

All other passengers have been been evacuated from both trains.

The crash happened near the village of Llanbrynmair, in Powys, at around 19:30 BST on Monday.

The services involved were the 18:31 from Shrewsbury to Aberystwyth and the 19:09 from Machynlleth to Shrewsbury.

Also in The Mirror with two pictures which to me show 2 x class 158 units on the same line having come into full face contact.

Despite being reportedly at a low speed, one life has been lost. Over a dozen taken to hospital.

Early reports that low adhesion may be to blame.

The bereaved and injured are no doubt in our thoughts.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

I read that the gentleman who passed away unfortunately suffered a heart attack, but wasn't physically injured in the crash itself. No doubt the shock was a contributory factor however.

From Wales Online

Quote
Jan Chaudhry-Van Der Velde, chief operations Officer for TFW spoke to BBC» (British Broadcasting Corporation - home page) Radio Wales and says the Rail Accident investigation team arrived at the scene last night and their investigation continues today.

Mr Chaudary said the trains were at a section of the Cambrian Line. The line is largely single line, he said, and where trains need to pass they use a passing loop, like when you have a passing place on a single track road.

He said he thinks the line will remain closed today but trains run from Mach to Aber and Mach to Pwllheli. There are replacement buses otherwise.


Quote
The Rail Accident Investigation Bureau team arrived last night but will continue its investigation during the day. Mr Chaudary said they will deliver a short bulletin summary of findings usually in the first few days and a fuller report in several months.

He said disruption will continue until the RAIB (Rail Accident Investigation Branch) have completed their work of collecting evidence. TFW will then need to remove the trains and return them to the depot for repair and Network Rail will have to inspect the track. That will, he said, take a few days and he warned people to check before they travel.

I should not start reading anything into Network Rail "inspecting" rather than "repairing" the track should I ...

Varied reports suggest a "slow speed collision" and "we went from 40/50/[60] mph to stopped in an instant"; which strikes me as a discrepancy that no doubt will be clarified.

Collision  involved 158824 and 158841 one of one of the drivers was trapped in the cab and .

Speed at impact was 22mph been reported on other forums. But staff saying it was  wheelslip which has caused this accident basically a similar incident to Salisbury a few years ago.

Thoughts are with everyone involved including the emergency services as the location is an extremely difficult place to reach

The two trains involved were not derailed and both involved were moved to the loop at the summit at Talerddig where they currently remain.  At Llanbrynmair there's a very brief break a good couple of miles into the continuous steep descent from the summit. The point of impact is one of the few places with relatively straightforward road access.

Streetview of the location from the adjacent A470 bridge. Google has the road as still closed for some reason.

*Edit* They were not moved... data from the signalling systems was displaying both trains in the passing loop at Tallerddig.

Apologies to Anthony215: my last post landed at the same time as yours and I did not intend to sound brusque. The A470 closure - it has an issue with a collapsed retaining wall and this may indeed have complicated the access to the site from the point of view of the emergency services.

Later BBC» (British Broadcasting Corporation - home page) report here https://www.bbc.co.uk/news/articles/c5y0yg7m8meo

Includes a picture of the scene, which I appreciate some may consider inappropriate, but posted with a clean conscience as it is already published via a reputable news outlet.

The crumpled state of one cab is clear. I wonder why one cab suffered such damage whilst the other cab looks almost undamaged.

Ah, also, a photo shows the site of the collision by a layby on the A470 some way up from Llanbrynmair. It's far closer to Talerddig, shortly after the deep cutting west of the passing loop.

Two streetviews, of the location and also from the overbridge at the west end of the cutting.

The Sectional Appendix gives a Mileage for Tallerdig at 61m 26ch.  Just on the Machynlleth side of the summit

I believe Llanbrynmair is at around 65m, reading that gradient profile

BBC» (British Broadcasting Corporation - home page) Story updated - following extra text:

Quote
Earlier on Monday TfW advised passengers its services were running at reduced speeds through Dovey Junction station - which is on the same line - because previous trains reported the track was "extremely slippery".

The operator suspended all services on the separate Heart of Wales line on Tuesday "until further notice" due to "poor rail conditions".

The loop's at the very short flat bit at the top of the climb. Google Streetview has imagery from the level crossing there. I'm trying to recall the wording on the board at the start of the descent, to the effect: "All goods trains to stop dead here and pin down brakes". It can't be a million years ago that it was removed, perhaps when the line's mechanical signalling was replaced.
