Drama on Hemerdon Bank | 7029 "Clun Castle" stalls on 'The Great Western Railway (1Z48)' 11/05/2024

Автокөліктер мен көлік құралдары

BR(W) 4073 'Castle' Class - 7029 "Clun Castle" would grind to an unfortunate stand on Hemerdon Bank, while working ‘The Great Western (1Z48)’ 60th Anniversary Tour, requiring the aid of BR Class 47 - D1755 / 47773.
The tour, chartered by Vintage Trains, would see 7029 retrace some of the route traversed by the ‘Ian Allen Great Western High Speed Railtour’ of 1964, which had the reporting code of Z48. The original running would become the swansong of ex-GWR mainline steam under British Railways, with the tour working the from London Paddington to Plymouth via Westbury, and back to the capital via Bristol Temple Meads. Four ‘Castle’ Class locomotives were selected to work legs of the tour: 4079 working London - Westbury, 7025 working Taunton - Plymouth, 7029 working Plymouth - Bristol, and 5054 working Bristol to London. 4079 failed at Westbury with melted firebars, with ‘Modified Hall’ Class - 6999 substituting for the leg between Westbury and Taunton. The tour would be famed for some exception high-speed running across the Ex-GWR mainlines with BR making every effort to ensure its success, including the cherry picking of the ‘Castle’ locomotives in order to provide the best of those available, providing two firemen per loco, and obtaining the finest quality Welsh coal available.
This 60th anniversary edition would be split over two days, with 7029 working from Birmingham to Plymouth via Oxford and Bristol on the first day, and then retracing its original allocated route from Plymouth to London over the second day.
Departing Plymouth on time on the second day, 7029 would stall on the harsh 1-in-42 gradient of Hemerdon Bank as it approached the summit, viewable from Ledgate Lane. Class 47 - D1755 / 47773 would then be dispatched from Plymouth to provide assistance. Rumours circulating suggest that lineside foliage caught the butterfly pressure release valves for the vacuum brakes on a couple of the coaches, causing a loss of pressure; enough to drag the brakes on the effected coaches, but not enough to show any indication on the gauges. With no indication of the problems at hand, and assistance immediately available, no attempt was made to restart the train before the 47 arrived.
All footage filmed on Saturday the 11th of May 2024.

    A huge shame that Network Rail's lack of maintenance in allowing branches to foul the loading gauge and clip the roof level brake 'butterflies' (partly putting the brakes on) brought this train to a stand. If the diesel had not been following this would have been far worse.

    if, big if, proper Welsh steaming coal had been available (no such now) the smoke would not have been thick black & the heat would have been appropriate to this anniversary outing. With the embarrassment of butterfly valves or not. Nb: The southbound steam express services ascending to Whiteball tunnel on Wellington Bank were always ‘banked’ with a steam push from Wellington. My great uncle was Foreman Ganger on the section & lived in the Beam Bridge railway cottages (long since demolished) right next to the bank when I was a child. {That was a thunderous noise for a five year old!}

    I'm an East Coast man, and it would have been so easy to start laughing at the GW; however, I think it was obvious that 7029 had a tenderful of bug dust here. The fact that the loco ran at all with that stuff is a miracle.

    Two reasons: 1. A big selling point for this tour was lack of diesel assistance, 47773 was supposed to follow the train without being attached to it all the way to London. I don't personally care about this, since assisting diesels are normally only there for shunting purposes and only push when they have to, such as situations like this one, as well as the diesels typically matching the train and being heritage locomotives in their own right, but there's a good amount of vocal people that do take issue with them being on there and it not being there ensures the Castle is completely unassisted to anyone who would otherwise doubt. 2. Even if this wasn't the case, the South Devon Banks have very strict load requirements for steam specifically because of situations like this. The Castle's maximum permitted load over the South Devon Banks unassisted is 9, which is what it has here, 7 passenger coaches + the GUV water carrier and Support Coach for 9 coaches total. It would've barely made it over the top anyway, dragging brakes were enough to make it stall. The 47's weight would push it over that unassisted limit.

    Nope, Castles can have 9, that's the load 7029 has here. I think it's different depending on if it's a single or double chimney one, so 5029 might be limited to Load 8 but 7029 and 5043 can take 9.

    @bobingram6912 One of the selling points for the tour was the fact it would be unassisted over the Devon banks in both directions. Thankfully, Vintage Trains do keep their Class 47 nearby on excursions should something like this occur. Cheers!

    And what we don't know is what happened in the 10 minutes before you see the engine. Was there a signal check further back that ruined their run at the bank? That could also account for it, because a Class 7 engine should be capable of taking 9 coaches up Hemerdon with little trouble.
