I remember in the early 60's seeing Tangmere's sister loco City of Wells with wheelslip at an Open Day at Eastleigh works whilst not pulling any coaches. Bulleid pacifics were well known for slippage. Great looking locos though. Seeing a 'Spam Can' would make my day.
@DRS37412 The heavy load caused her to slip. Quite a weight for her to lift out of Lincoln. This trip turned into a nightmare. I was on it and got home at 1.30 this morning!
Oliver Bulleid's locomotives were prone to slipping. Witnessed an extraordinary sight one day at Weybridge in the mid 60s. The S&T installed an extra signal on the Down fast in the station area. Arrives next is a Bulleid Pacific WCC. + train.Held at this same signal, then cleared by the Bobby, only on starting, massive non adhesion and driving wheels spinning like a Catherine Wheel. Not being an expert in the art and science of driving/firing, I cannot comment on what was correct and what wasn't but only to act as a witness as to what I saw. I never saw such a thing again. By July, 1967, the opportunity had passed into history. That extra signal has also gone, I understand. Alistair
Steam locomotives are weakest at starting out with a train they make the serious power at speed, with the Johnson bar in the "corner", he was more than likely feathering the throttle for power which is an art form it is a lot easier to feather/trim the johnson bar but that is only done after speed starts building.
Two thing cause this: (a) light axle load (to not damage the delicate bridges in the West Country) and, (b) massive starting torque due to its being a three cylinder loco.
Why? Oh why, is this locomotive being coupled to twelve coaches? It was designed for 8 with a maximum of 10. They also had a low axle weight to accommodate the small bridges in Kent and the West Country. Put these two facts together and excessive wheel-spin is the result. Albert Hardiman (my uncle) regaled me with tales of how in the last days of steam service he and other drivers took great delight in running these at over 100mph whenever the opportunity arose. I recall that as a passenger it was rather frightening to be bouncing along at that kind of speed. From the platform at Grove Park I was convinced more than once that the whole lot was going to leave the rails and fled upstairs to get out of the way.
Were on earth did you get that ridiculous notion that a Class 7 is only intended for 8 coaches, or that they had a low axle weight due to bridges in Kent etc. You need to read "Bulleid Pacifics at work" by Colonel H.C.B Rodgers OBE. Published by Ian Allen 1980. As a qualified steam locomotive driver I will only say that you know absolutely zero about Bulleid Pacifics or trains in general. Get a life.
Oh the Bullied Pacific's and the Bullied chain driven valve gear. The wheel slip was prone to them as they were some what to light. Some even shredded the chains right off, that why BR rebuilt them with the Walschaerts valve gear.
Where on earth did you get these bonkers ideas. I suggest you read a qualified book on the design and operation: "Bulleid Pacifics at Work", by Colonel HCB Rodgers OBE, published by Ian Allen 1980. Do you honestly think that they would allow Spam Cans to operate on the mainline today if what you say had any truth in it?
@scotsguardsman100 I got on at Woking but had to get off at Farnborough on the return as I had missed the last train back from Woking. Got a Taxi from the station back home. It would have been a better run if the Class 37 had not been attached on the outward run as this caused most of the problems during the day.
The problems that Tangmere had at the hill and leaves at Martin Mill, was wheel slipping, Is she a light engine? Or do they put too much weight behind her? I always thought the steam engines with their bulk were a lot better in slippery conditions like the big diesel units, but unlike the electric lightweight coach units.
Tangmere's class had (some had it removed, but Tangmere appears to still have it) a problematic valve gear system, which often leaked or stretched, resulting in such wheelslip. On top of that, another commenter claims that yes, she is overloaded, which may very well exasperate her existing problems.
A reg DID jam on a loco once. I know it's common, but this is a notable one: The Blue Peter, which is the sole A2 class survivor, suffered damage from a catastrophic wheelslip... The driver opened the regulator too early, thinking that the locomotive will stall on a hill. Due to this, the locomotive wheelslipped uncontrollably, causing the boiler to prime. It carried water of the regulator valve and jamming it open. According to another TH-cam video, the wheels went at an equivalent of 140 miles per hour. Not kilometers, miles. The fastest record for a steam locomotive is 125.88 mph, which was on the Mallard. So the WHEELS broke the speed record.
Tyler Haney the valve gear and motion actually was completely destroyed when it happened. Ive seen what remained of it (some parts were reused) and it is incredible the amount of force that must have gone through them
Bulleid pacifics actually don't have the chain driven valve gear anymore. they were removed and replaced. there is talk of retrofitting one but at the moment they all use standard valve gear
***** Tangmere still has her chain driven valve gear, along with all the other spam cans that are still in their air smoothed casing. The re-built examples (eg, Braunton) don't however.
Alistair Foden sorry to break it to you man, but none of them have chain valve gear. They were rebuilt with walschaerts valve gear because the chains streched
I'm surprised the SR ever managed to run trains anywhere with Bulleid's pieces of junk "pulling" them. Perhaps it would have helped if the passengers got out and pushed.

Michael Brandon Terrible pollution and potential track damage, these locomotives need to be sliced with cutting torches and melted down as scrap.

Nice one, thank you. I see the 'banker', shown in all the outward clips, was missing. Also, driver's left hand was in view just about the entire shot.

Great video shame about the whistle i was hoping to hear a better one.

Why was this departing from the up platform ? Years ago down trains departed from the down platform!
Way to many coaches!!!
Bulleids were always light on their feet.

Obviously not a 70A driver.
I didn’t know Tangmere was still around that’s a nice surprise she’s quite a poignant one for me.
Well that what you get of spam cams
Itsv about time they lernt to drive them properly
Could you drive it properly? No. In any case, you'd need to learn to spell before driving a locomotive..
