Haahaa, I remember St Pancras as a kid - InterCity 125s were the Daddies. The whole station was filled with a dark smog. You could literally taste the diesel! It’s incredible how well they transformed St Pancras & Kings X. Hope the new Euston brushes up well too.
@@tomgauntlestrange Yep, and get some Nameplates made up for one power car of your choice..... "Greta Thunberg"..... I will happily be there with you at the unveiling too !!!!!! 👍👍👍🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Notice how BMW put fake engine noises in their I8 electric sports car? They understand the role of sound when it comes to fun factor even if it can be perceived as noise pollution.
The feeling of excitement for the passenger is great. Can you imagine how it must feel for the driver, opening the taps to over 4,000hp? Well, let me tell you, it makes the hair on your neck stand up, and the reason I know, is because it was me driving that HST....
very sad these days being a rail enthusiast having to live in the past. all and i do mean ALL new rail stuff is cheap and nasty and stupidly expensive to travel on.
Looked like a normal departure for that type of engine to me. This was a very common sight on the BR WR / GWR with class 43 HST services. It's what you get when a diesel-generator set (with that type of engine) goes from sitting running with no significant load, but then has to supply lots of power to the traction motors to haul the train forward at what is a fairly rapid rate of acceleration (compared to other traction in service when it was designed).
It also sounds like the turbocharger is huge, so it takes a long time for it to spool up and supply the correct amount of air needed to burn the diesel oil supplied.
@@Runeakb There are 2 turbochargers, made by Napier. They are about the size of a small car engine. That smoke you see is a mix of oil travelling down the valve stems, past the seals and unburned fuel. The black smoke is what you see when the turbo is slow to spool up. Look at a newly overhauled Valenta (none available now, so look at old videos) and you'll see they are darker. This is a shocking state of maintenance.
Mark, I don't know how old you are, so you may not remember them when new. Back then they were a little smoky, as all diesel engines of the era were. But nothing like this. You have a mix of turbo lag, which results in black smoke (partially burned fuel) and this was the most common colour when they were being properly maintained. This is something else; this is a mix of oil seeping past the valve stem seals, or even turbo seals, together with unburned fuel, which is indicative of poorly maintained injectors and / or injector timing error... I am not sure if the injector timing point is fixed or variable on the Valenta- perhaps someone could confirm.
@aye480bat720 I've just thumbs upped the shit out of your comment. What you said makes perfect sense. Don't forget the other benefit to your idea though, the HUGE creation of jobs. :)
East midlands line, good old I C 125 lives on in a new livery and company name. I have seen a cold start at Paddington, the diesel smoke is soot black. staining the lovely iron work with carbon deposits.
I noticed that some of the hsts gave a high squeal/scream mutated sound rather than the usual scream, particularly the MML(when it was)units. That Hornby HST was another one that give a similar note to this.
I really wonder is it the weather or do are all the British diesels terrible? Black smoke when departing or accelerating is normal, it means rich mixture in cylinders. But blue or grey smoke means there's something in engine really wrong! And I didn't see any video that a British diesel doesn't smoke blue or white or grey!
@@steamlocomotivesltdjamesh6760Think it's to bring them up to 21st century rules that (afaik) demanded LED running lights. Most companies did the twin headlight arrangement, however the Midland region went with this triple light setup
