I was thinking exactly the same thing !! So many of the (preserved) Deltic videos, and they are all running one engine ! Like The Beatles if Ringo and George didn't turn up !
I were on this,can`t tell you how emotional it was racing down the ECML in a full BR Blue rake,and a Deltic on the front,never got the chance to ride behind them when they dominated the ECML, so this was a big tick on my railway bucket list..
The combination of that fantastic diesel engine immediately followed by the groove of the coaches was quite a lovely aural feast 😊. Thanks for sharing.
I agree. The gentle roll of the carriage and the rhythmic click-clack of the wheels over the joints were guaranteed to send me into a deep sleep. Now all you get is intrusively loud announcements over the speakers.
Good to see it's not just a man thing ! I remember seeing them in York station in normal service in the 60's they sound like a small war going on ....mega , my favourite diesel.
In the Seventies, I remember walking up the steps from the Underground at King's Cross and being able to hear and feel when a Deltic was at a platform with the engines idling. Awesome!
I think that's a really nice rhythm, maybe a modern kind of train song.....(I know the deltaic is years old but its still more modern than other diesels)
Craigentinny was a carriage depot. Trains were brought to Waverley Station by pilots. Main line locos never went near Craigentinny, their depot was Haymarket MPD.
Sounds good but I still reckon you can’t beat all our EMD’s especially all the 567’s and 645’s in all our loco variants here in Victoria (Aussie) that thing sounds more like a 671 with an Allison auto in an old Kenworth Lol! Ahh I’m only joking that’s actually not a bad jigger and sounds pretty good I take it it’s one of those triangular Deltic things probably one of the better things you pommies have made
I was just thinking too, I'm not surprised they built it as a 2 stroke. Imagine if they'd designed it with twin OH camshafts per cylinder row making 6 camshafts & 4 valves per cylinder! And that would be 144 valves per power unit & 288 valves per Deltic ! Of course they could always borrow from Koennisegg's free valve idea but it'd still be hideously complicated & expensive to service.
There are still quite a few 2-stroke diesel engines in service on the railways. Notably, the EMD 710 12 cylinder type is in the class 66 class, for freight use. It’s power output is similar to the twin engined Deltics. Also, 2-stroke is much used in marine engines, such as the rather large ones in container ships etc.
I went to Markle level crossing to see it! I waited 45 minutes in the cold, eventually gave up and went home via Drem to see if it was anywhere, and found it idling on the main line just after the station, with train staff crawling around the bogies with torches. Hope they manage to repair it soon; I heard it was a fault with the traction motors.
The class 66 makes hell of noise too and that's just to get it to move .Deltics sound like that one engine or two and it needs that power just to get it to move it's how they were built if some people dont like the way a driver has to get Deltic going take it up with the people that built it
Actually I must amend my previous comment. I was forgetting that each opposed pair of cylinders shares fuel mix inlets & exhaust outlets so it would actually be 72 valves per power unit & 144 per Deltic. Boo! Doesn't sound so good now , but it'd still be impressive!
Correct. But it's an opposed piston arrangement so there are two pistons per cylinder, three cylinders per bank and six banks per engine. Thus for two engines we have 2×1×3×6×2=72 pistons, which in all honesty sounds even more impressive than 36 cylinders.
The Deltics were high maintenance and very complicated. So complicated that the depot fitters had to call on the manufacturer regularly to sort out problems. The reason the ones still running today smoke excessively is that there’s no one around today who can maintain them properly. They struggled to maintain them when they were in service, so it must be an even bigger problem servicing them now.
Think I'm right in saying that the scavenging/combustion air is delivered by shaft-driven lobed blowers, not turbochargers, so the amount of air supplied is directly related to crankshaft rpm, so doesn't suffer from any "turbo-lag"
@@drummerboy1390 The Napiers are well understood and a lot of knowledge has been handed down. The main reason I believe is simply that in preservation the Deltics aren't operated to intensive schedules: It's well known that oil collects in elbows etc within the exhaust lines if the Napiers are idling or on low power and not working at full operating operating temperature most of the time.
I wanted to know why don’t dig a tunnel and do an extension for the main line Train so they extend the new abandoned underground stations. Why couldn’t they use the part D78 Stock train doors on the sides and also restructure the front face of the A60 and A62 stock that includes the class 313, class 314 and class 315 remix and make them all together and also redesign them an overhead line and also make them into six cars per units and also having three Accessible Toilets on that six cars per units A60 and A62 stock trains and also convert the A60 and A62 stock trains into a Scania N112, Volvo TD102KF, Volvo B10M, Gardner 6LXC, Gardner 6LXB and Gardner 8LXB Diesel Engines and also put the Loud 7-Speed Voith Gearboxes even Loud 8-Speed Leyland Hydra cyclic Gearboxes in the A60 and A62 stock, class 313, class 314, and class 315 and also modernise the A60 and A62 stock and make it into an 11 car per unit so it could have fewer doors, more tables, computers and mobile phone chargers? A Stock Train and also having 8 DisaAccessiblelets on those A stock trains. why couldn’t we refurbish and modernise the waterloo and city line Triple-Track train tunnel and make it bigger and extend it to bank station, making it into a Triple-Track Railway Line so those 4 European countries such as Germany, Italy, Poland And Sweden to convert the waterloo and city line Triple-Track Train tunnel into a High-Speed train? The Third Euro tunnel Triple-Track Train line to make it 11 times better for passengers so they could go from A to B. then put the modernised 11 car per unit A Stock and put them on a bigger modernised waterloo and city line Triple-Track train tunnel so it could go to bank station to those 4 European countries such as Germany, Italy, Poland And Sweden. The modernised refurbished 11 cars per unit A stock could be a High Speed The Third Triple-Track Euro Tunnel Train So it is promising and 37 times a lot more possible to do this kind of project that is OK for London Germany, Italy, Poland And Sweden. oh by the way, could they also tunnel the Triple-Track Railway Line so it will stop from Buckinghamshire, Hertfordshire and Essex so that the Passengers will go to Germany, Italy, Poland and Sweden and also extend the Triple-Track Railway Line from Bank to Buckinghamshire, Hertfordshire and Essex Stations so that more people from there could go to Germany, Italy, Poland And Sweden Easily. Why couldn't they extend the Piccadilly line and also build a brand-new underground train station so it could go even further right up to Clapton, Wood Street and also make another brand new tunnel train station in Chingford and could they extend the DLR? All of the classes 150, 155, 154, 117, 114, 105, and 106, will be replaced by all of the Scania N112, Volvo TD102KF, Volvo B10M, Gardner 6LXB, Gardner 6LXC and Gardner 8LXB Diesel Six carriages three disabled toilets are air conditioning trains including Highams Park for extended roots which is the Piccadilly line and the DLR trains. Could you also convert all of the 1973 stock trains into an air-conditioned maximum speed 78 km/hours (48 MPH) re-refurbished and make it into a 8 cars per unit if that will be alright, and also extend all of the Piccadilly train stations to make more space for all of the extended 8 car per unit 1973 stock air condition trains and can you also build another Mayflower and Tornado Steam Locomotive Companies and they can order Every 17 Octagon and Hexagon shape LNER diagram unique minor no.13 and unique small no.11 Boilers from those Countries such as Greece, Italy, Poland, and Sweden, can they make Mayflower and Tornado Steam Locomotive speeds by up to 117MPH so you can try and test it on the Original Mainline so it will be much more safer for the Passengers to enjoy the 117MPH speed Limit only for HS2 and Channel Tunnel mainline services, if they needed 16 Carriages Per units can they use those class 55’s, class 44’s, class 40’s and class 43HST Diesel Locomotive’s right at the Back of those 16 Carriages Per Units so they can take over at the Back to let those Mayflower and Tornado Steam Locomotive’s have a rest for those interesting Journeys Please!!!, oh can you make all of those Coal Boxes’s 16 Tonnes for all of the 117MPH Mayflower and Tornado Steam Locomotive’s so the Companies will Understand us PASSENGER’S!!! so please make sure that the Builders can do as they are Told!! And please do something about these very important Professional ideas Please Prime Minister of England, Prime Minister of Sweden, Prime Minister of Germany, Prime Minister of Italy, Prime Minister of Poland and that Includes the Mayor of London.
For some reason my camera wouldn't automatically refocus while filming. It was rather amateurish but I think I may have forgotten to set it to that mode.
Tom Lowe: Tom if you are replying to my last comment then I hope a diagram of the Deltic layout helped. It's a pretty unique design concept that can be hard to fathom how it functions when you first look at this engine.
Two 18 cylinder Napier Deltic lumps under that bodyshell When this came out, there were no single engines that could put out 3300 hp and fit the British loading guage. Also the main generator (s) being a dynamo (DC) could only handle up to 2750 hp, alternators do not have this restriction. There were three twin engine loco classes built. Deltics (class 55) Warship (Class 42 / 43) and Westerns (Class 52) (My apologies if I've missed any out)
@@g8ymw Clayton type 1 (Class 17)?. The "thing on the rear" is a service coach used for looking after the loco and support team. I think it has a generator but does not supply any traction power.
abberationify you are wrong the pistons are arranged in 3 groups of 6 3x6 =18 in a triangle and if you do some research you'll find I'm right on this occasion
Tom Lowe: I think you might need to do some more research on this engine. You are aware, I assume, that this is an OPPOSED PISTON two stroke diesel formed of 3 banks of 6 cylinders in triangulated or delta formation with a crankshaft at each corner of the triangle. If you were looking at the engine end on, each triangle consists of 3 cylinders (one cylinder forms one side of the triangle) with a crankshaft at each corner but has 6 pistons within those 3 cylinders, worked from each of the 3 crankshafts, allowing 2 opposing pistons working in each cylinder ( the 2 pistons come up to each other in the cylinder to create the compression for the compression/ignition sequence of the two stroke cycle). Now there are 6 triangles of 3 cylinders making up the 18 cylinders, each with 2 pistons per cylinder, making 36 pistons for each engine. The meaning of an opposed piston engine dictates that there are 2 pistons working "opposite" each other in the same cylinder, so if there were only 18 pistons it would only have 9 cylinders (Napier did produce a 9 cylinder (18 piston) version of the Deltic engine which was used by BR in a small class of "Baby Deltic" locos which were not very successful). Could you also explain to me why, if the opposed piston 18 cylinder Deltic engine had only 18 pistons, it needed 3 crankshafts (think about that one). There is plenty of information and schematic diagrams of this engine on the net.
I remember these at Peterborough, we used to get the East Mids Ranger card then blag rides up & down the ECML behind the racehorses.Summer holidays were pretty good back then, non of this eco climate BS, pronouns, LGBTQ, gender bender misfits, just straight folk & gay folk pure and simple.
The atmosphere under the low slung Waverley Bridge, at the other end of the station, with a big old diesel idling for minutes on end, can get quite, well, aromatic. Just like BHM in the 1980s!
Did you mean Junkers? It's true that Napier obtained licences to build two types of Junkers engines, and made a small number of one design as the Culverin, but the Deltic was Napier/EE's own design, although it was influenced to some extent by other Junkers engines from captured aircraft. I never heard of any Maybach influences though!
