For the true effect, you need to be working on the steam heat boiler, between the engines, when they open up to full power. You actually feel your internal organs try to find a safe place to hide.. I will never forget it.

Wow. Sounded like a bucket of marbles in a paint shaker at first, but really it sounded very smooth and powerful soon after. It fired instantly, and the little blip of the throttle said a lot. Very cool.

I live in Doncaster I remember seeing a deltic pull into Donny station felt it in my chest magnificent feat of British engineering

The exhaust piston leads the inlet piston by 20 degrees, and the only way to get it all to work is by the bottom crankshaft rotating in the opposite direction to the two top crankshafts. A work of geometric genius.

Nice mug of Builders always at hand. I love traditions.

Beautiful start up! Liked the gush of clag that billowed out! :)

What a great sound, I remember watching these as a kid (late 60's) at Finsbury Park (London). You could hear one coming from a mile away. I can't believe they chopped up about 15 of these for scrap metal. Does anyone know whether any of the remaining locos are used for "Driver Experiences" I drove a 37 class at Llangollen Railways last Sept it was brilliant, while on hoilday from Australia, and I would come back again for a crack in a Deltic.

Amazing how easily these deltics start, meanwhile the class 37's and 50's painfully splutter and smoke into life !

1:07 Job done! Time for a cuppa.

Love the sound of the Deltic. Like no other.

What a gorgeous machine!

The only way to achieve the correct piston timing was for the bottom crankshaft to rotate anti clockwise. There isn't enough room, or I would have shown you a timing diagram. Anyway the phasing gearbox easily absorbs any difficulty. The engine is still running happily on H M ships in the Royal Navy.

Watching these at full chat from site of Thirsk Junction on ECML was sensory overload! Awesome stuff 😊

Jalu The name Deltic comes from the Greek letter Delta. Deltic, is the name of the engines but has also become to mean the Class 55 locos. The arrangement of the cylinders is in this form, namely a triangle, such that there are crankshafts at each corner (3 in total) and 2 opposed pistons in each cylinder. So the basic unit is 3 cylinders with 6 pistons, but practically, the engines were produced in 9 cylinder and 18 cylinder versions.

BEST loco EVER built IMHO.

As a second man in the 70’s driving these to re-fuel at Kings Cross was our first experience at the controls we were only supposed to use one engine but we always used two, we would crack open the throttle to full and be pushed back in our seats and cover the inside of KX canopy with black fumes . The only downside was rattling along at a ton and the steam heating boiler starting to play-up as it was between both Engines.

why do these locomotives always have the engine compartment windows open? i'm guessing it's to do with the amount of heat generated by the two engines so therefore it must get extremely hot in there especialy when the engines are being run at full load.

Thats true; the infamous blue 'Old Oak Haze' was nothing compared to the smog that emanated from the KX stabling point!

are you getting one for your layout

smooth

Gizza go !

I think you are referring to the fact that two crankshafts rotated in one direction and the third in the opposite direction. I'm not sure the reason but I think that this was crucial in the operation of the Deltic and I think it was all to do with achieving an effective scavenge. The opposed pistons operated slightly out of phase with each other, in that way the fresh charge scavenged out the previous charge then gave some supercharging, before compression started.

Michel Linschoten Yes, they do sound quite busy don't they? I was in a rail museum in Portland, Oregon yesterday that has a loco that looks very much like the Deltic but is not double ended and has a single V-12 ALCO. Manufactured in the early 1960's. Deltics are similar to a Fairbanks-Morse engine but only two cranks on a straight engine. They were deemed to be too complicated by the old line mechanics. We have a small submarine here that has a Fairbank-Morse of the same opposing piston design. They are fun to listen to.

You can't be serious at KX it was midday before you could see though Gas Works tunnel after the morning diesels left.

well said not to forget that the private train operators get more money now than BR ever got.

How are these engines started? Do they use an explosive charge like some other two stroke diesels such as the Field Marshal tractor? It certainly seems to start more abruptly than when a conventional started motor or donkey engine is used. I heard three bangs and the Deltic has three crankshafts unless I'm mistaken. Could these three bangs be an explosive cartridge being activated for a cylinder in each crank or am I barking up the wrong tree?

Headlights are a complete waste of time. Yes, they advertise your approach, so anyone on the tracks has time to get off. But the driver can see NOTHING outside of the beam. The night vision is totally destroyed. If he sees an obstacle within the beam...he is far too close to take any useful action. I read a similar comment the other day regarding the Titanic...1912..something to the effect that a headlight would have shown the iceberg earlier..... Dear-oh-dear.

Needs to be louder! :)

So, all it takes to start one of these is a hammer and a cup of coffee?

Not strictly true. Not so much a primary and secondary...more of 2 of the same engine/generators each rated at about 1650 hp.

Just one. Class 55s were usually driven on the main line using both Diesel engines but sometimes on slow duties only one was used. Because the engines were, I understand, used in sequence (not in parallel) the second engine could get `oiled up' with too much idling and so was often shutdown on slower, less arduous duties.
