Great video. The Deltics only smoke like that when they've been cold for a bit. It's unburnt oil. Once they get going for a while there's not so much smoke output. There's no other train that makes a sound like the Deltic.
It would be smoking because it is operating without a load - it's not pulling a train. This means two things: 1) the exhaust gas volume is lower, so the partly burnt oil is a greater fraction, and 2) the combustion temperature is lower, and so burning the lube oil less completely.
@keithammleter3824 Smoking caused by inverted pistons filling with piston cooling oil,depositing excess oil on upper side cylinder walls at low revs.
Hold onto your hat indeed! And perhaps a gas mask :) I’ve always loved the Deltics. They emanate such aura of controlled power. Plus a family connection with my father having worked on Napier Deltic marine engines in the 1950s.
Awesome machine. I remember being at York station once, with an HST on one side of the platform and a Deltic on the other, with me stood in the middle. Both, for some reason, were revving the nuts off each. Incredible noises and so LOUD!! Couldn't hear properly for the rest of the day, but wouldn't have missed that experience for anything. Awesome machines both.
Through the 2 stroke smokey glag is a masterpiece of it's time, and just listening to the turbos and that exhaust howl is enough to evoke memories from the past!
How environmentally friendly! We used to jump into the brambles out of the way of a very slow (as in 15mph) Deltic on an old branch line used by industry about 40 years ago. I can still remember vividly the rumble in the ground as it went past!
It's interesting that some smoke from a train upsets so many people yet an airplane dumped over 70 tons of unburnt jet fuel over New Jersey a few days ago to make an emergency landing with little comment from anyone. That's pollution. th-cam.com/video/lcB0y_bRsPk/w-d-xo.html
@@jessicaandtrains7768 EXACTLY!....Also, it's ONE Deltic....Just ONE. It's not as if there's a million of them running 24 hours a day, 7 days a week, 365 days a year. Its just.........ONE.

Also what you can't see is carbon dioxide contributing to greenhouse gases and global warming climate change? These polluting locos must be broken apart and the scrap recycled to make cleaner traction.
I just want to put it out there that the smoke seen is not soot, carbon, of any other greenhouse damaging emission. It is unburnt lubricating oil that has been heated to a vapour state.

Could be caused by a number of things: damaged piston rings, valves, injectors, or, and must likely in this case, a damaged oil seal on the induction side of the turbo [exhaust side is another candidate]. Upshot is that this is not the usual exhaust seen from a normal healthy Deltic loco, no matter how lightly loaded it is working. So, yeah boo sucks to all those bashing the environmentalist drums, that's nothing what they looked like when in regular service, and what you see is not responsible for climate change. The only greenhouse damage it's doing is to make the glass sticky so that dust sticks to the panes and residues the light coming in.
I think it needs a bit of attention but fair play to them. To get 2 working deltic engines running again on a mainline train and to pass mainline tests. They've done a great job.
Yep, that's a Deltic. Even as a Yank I can tell - that combination of smoking like a steam engine, noise like a jet engine, and horn like the driver nicked it off a penny farthing just can't be beat anywhere in the world. ^.^ That had to be a museum piece being used to haul another unit back to the museum (or the down shops).
@@owensmith7530 Yes i must agree. Both tops in their day. My favorite machines also. Both private ventures both unconventional both revolutionary both twin engines both high power to weight ratio both loved by crew both hated by fitters!!
Don't feel bad the GE four strokes in some of our locos smoke just as bad. When WAGR had the two stroke Crossley HSTV8 powered X class locos the only time they were shut down was for servicing. Keeping them at operating temperature made them last much longer and they were always ready for work.
Yes it's quite amazing to see. When you consider a class 66 is a 2 stroke but apples and oranges. Not really comparable any any way. And yeah amazing to see it on both engines. I thought they'd only ever be allowed to run one these days.
This one is operating without pulling a significant load, so would be expected to smoke more. Combustion temperature low, and exhaust gas volume low. Both make incompletely burnt lube oil more obvious.
I know they have two 2 stroke engines but this one is burning oil.Turbo intake compressor seal leaking.Common problem.Its possibly not just running on diesel but oil aswell.If its too bad then it could start to runaway.

My uncle knew some of the engineering team that built the Deltics. When I was still a teenager he told me that they had a circular test track and that, on occasions, the engineers would jump onboard a locomotive and go around in circles at the factory while they had their lunch.
What an awesome time! Wish those days would happen again. When British Rail led the way in new technology without the climate nonsense. Yes keep it clean but ignore the CO2 nonsense.
@@alex_ob1 the lie that is propagated about co2 being relevant in climate change and global warming. Used as an agenda to push through false green technologies and to tax an irrelevant molecule that is in fact essential to life on earth. More co2 makes the world greener which most people think is the reverse.
It's a shame the Deltics had such a short working life in service, just over 20 years. The Brush Type 4 (Class 47) and English Electric Type 3 (Class 37) have managed 60 years and 65ish years.
They only made 20 or so, only on the ECML , universal usage across the country didn't happen. Apart from 3 depots nobody could or had the tools or expertise to fix them
The problem is the engine technology, it could never achieve the energy efficiency (and low emissions) of a turbo charged 4 stroke diesel or the power to size and weight of a gas turbine, so Napier got squeezed out the market, however the Deltic does represent a rather glorious evolutionary dead end, if you are going to go you may as well go with a bang.
@@grahamariss2111 I don't believe you're right. On the question of efficiency, they were very efficient. They were very intolerant of poor maintenance, however, and the shops they were serviced in lacked sufficient trained crews. The uses outside of railways that they were marketed to were largely naval and military uses, also at a time when massive disarmament had killed most prospects. Questions of emissions really didn't come into the matter in the era that they were built and low fuel prices made fuel consumption also less of a consideration....
@Daniel Donaldson That is my point, they were a solution of their time, but as turbid charging bought diesel 4 strioke with sufficient power density for rail why would you stick with the Deltic with its higher fuel consumption. Now Napier stretched the power density but then it lost out as a patrol boat engine to gas turbines because of the simpler maintenance. it was dead end.
Reminded of a story I recall of someone who kept a deltic in pristine condition only to be asked if it could be loaned for a freight company. At commercial rates too. The story has to be a lot more complex than that of course.
Used to see these on the Reading line as a child in the 1970’s. Remember crossing the tracks and after turning round to see one thundering through. They built an underpass shortly after that.
Sound like great memories! There's a spot near me that had crossings and now has bridges. Probably because not everyone can be trusted. It's on a spot where trains travel at 110 mph. The current trains could probably do 125mph if they were allowed.
Alas no, the three cranks were geared together with the lower one rotating in the opposite direction to the other two to get the phasing correct. Something Napier struggled to get right until realising one crank had to be reversed. Fantastic British engineering.
27/4 23, Think there were Baby Deltics that preceeded these bigger cousins - used on Eastern Region suburbian routes which pumped out exhaust clouds on departure too. Numerically were D59 xxx. Don't think they were named - unlike ' Meld ' & Co.
There have been some problems with the engines. Maybe it's due to the old materials used. I don't know the details. One of the engines ran great. Very little smoke.

It must have just started, I don't remember them pumping out that much smoke unless they were just starting up.

It better not go into London, else it will have to pay the ULEZ charge.
Amazing 2 stroke beauty. Reckon it were going 70mph?
