Great video, brought back memories of my childhood when the sound of these pulling out of the station near my house on full power was as normal as breathing. The fact that the IC-125's endured for so long despite being introduced as a temporary (10 year) stop gap, is in no small part down to the superior engineering of the Paxman engines. A bit of nerdy trivia to support this - the Paxman Valenta was used (in sets of 4) to power the Royal Navy type 23 Duke class anti submarine frigates during the 1980's. The Navy's Invincible class carriers, including HMS Ark-Royal was fitted with 8 Paxman Valenta's. Yes you read correctly.....8 of the screaming ba...tards! The Valenta's predecessor (the Ventura) was used (In sets of 4) for electricity generation on the Royal Navy's type 42 destroyers during the 1970's and 80's (including the I'll fated HMS Sheffield & HMS Coventry that were sadly lost in the Falklands war. My work partner served for many years in the Navy as an engineer on type 42 HMS Liverpool. He says he hated the Paxmans, but then he drinks black decaf coffee instead of tea! (weirdo ☕😎). Thanks for making and sharing this video. Younger people may not appreciate just how important the HST's were and just how much they pulled British Rail out of the sh..t back in the day.

Great video thank you for the insight. An enthusiast's dream job. If I was to do this (for free) it would alow proper techs like you to do something more complicated. It's funny how people hated the HST because it ousted the beloved Deltics but now they're going everybody realises what a fantasticpiece of British design and engineering these fabulous machines are. Only ever seen de-mounted HST engines tested before (at Crewe). The engineer was moaning that he hoped the customer (for the engine , one of the Virgin franchises) wouldn't mind that their engine was being abused by all the visitors getting to try the test rig. Some real ham-fisted 0 to max in a split second punishment ! The walk through brought back memories of Crewe open day during the time they were building the 43's. We got chance to do the walk on a nearly complete power car and I remember it being a bit of a tight squeeze past the cooler group. Like how all the tech turns into an analogue pen and grubby notepad at the end. I'll certainly miss the Paxman scream, even the 56's are going yank now. Waiting at Tollerton you could hear them leaving York Station!! Do the 222's get load banked as they are diesel electric just the same ?
I used to work on the 222s at Central Rivers , I never saw them get load banked , we would measure the crankcase blowby with a manometer with engine at full revs , cant remember what full revs was , probably 1500 or 1800 rpm , wasn't full load on the engine but we could tell if the was a broken piston ring in there . When I worked there they had problems with them dropping valves and breaking piston rings

Great vid! It wouldn't be that hard/expensive to set up a datalogger to measure all those temperatures continuously. Wouldn't even need to have a load bank then, you could collect the data whilst the engine is in normal use. You draw the data back to HQ using GPRS over the mobile phone network. Obviously no point now, but it still would have been cost effective to do ten years ago. Wouldn't have minded seeing some of the actual load bank. I imagine that must be quite a piece of work on its own, to accept and get rid of all that energy.
Is it possible to distinguish the noise of the various components that accompany the diesel? For example, is it possible to hear the sound of the alternator, compressors and cooling fans? Or is it all melted and indistinguishable?
@Wesley Holmes There's something about this Locomotive I really like and I can't quite figure out what it is. My theory is that it's Britain's most Beloved HST and it's 24 Litre V12 Diesel engine sounds amazing and it just looks cool. For some reason I always preferred this Locomotive in the GWR Livery and the CrosscountryTrains Livery.
1700V @ 780A. Three cables going over to the load bank. Is this 3 phase Delta? Whichever way it is this is a lot of heat in the bank. Air cooled? One monster fan heater if it is.
I can't remember the maths I think it was 1790v x 780amps and the cooler group would take 225 hp yes it was air cooled , it had 2 big air flaps that opened up on the roof everytime you powered it up . We used to set them at 2250 to 2300hp

@@davesawyer497 yes the engine and alternator was rated at 2250hp, it was the cooler group that would zap 225hp from the engine . The cooler group had a big hydraulic fan cooling 2 radiators

Great Video! We now have 43073 preserved at the Colne Valley Railway, great to see how the load bank is conducted!
The walk from the cab to the guard’s section is exactly like I expected it would be, even though I have never seen that before on an HST.
