Thanks for videoing the whole train as it went past, not just the loco.

Yes, I seemed to ride it a lot to York during the 70's too!

They sounded so good with the old Valenta engines

@@HotForgeChaos I have to agree. The new engines make them sound like a hamsters wheel when compared to the all screaming Valenta.....

They rebuilt the station a bit further down the line from the old one to allow for the increase in the service.

Odd, I love the sound of a Deltic horn it's perfect - short, sharp, and urgent, just as a pedigree racehorse should be..

Diesel doesn’t effect the ozone layer, chlorinated hydrocarbons do.

Inform yourself and don't listen to main stream media.

They're two stroke engines.

@@1earedwolf I always thought it might be something to do with oil on the injectors all the time Are two stroke engines naturally smokey all the time?

Nose trumpet.

No, these engines were rated at twice of those power used in the class 55, the napier deltic was used in MTB and mine sweepers with turbo's fitted and "battle power" setting of well over 3000hp and in those cased they could have been over fed, but in the class 55 they were normally asperated at 1650hp each (2/traction unit). What you are seeing here is an old girl with 100k's miles on her - and with 2 stoke diesel, you are going to get a lot of shit in the exhaust.

@@Tom55data "a lot of shit in the exhaust". How often does that need doing? 😊

The Deltic has double the power of a 37.

@I'LL BE BACK ! Just a frank observation...

@@SvenTviking I'm talking about the ability to get going from stand still - which requires more torque than power..

@@garethifan1034 A class 37 has more starting tractive effort than a 40. Perhaps more interestingly, a class 08 shunter has more tractive effort than a class 66!

the class 37 had a starting tractive effort of 55K lbf while the class 55 had a tractive effort of 50k lbf but the class 55 was double the HP. The class 37 in the UK are known as "tractors" - as they "pull anything.... slowly". The class 55 (known as a "bomber" from its noise) was designed as a main line engine and were limited to 125 mph intially, though this was down-graded to 100mph, much faster than the class 37. I regularly used the east coast main line in the UK in the 70s and 80's and you knew when the deltic was on the front - 13-15 coaches, and you were leaving London as some fair whack - while being pulled by the 37 or 42 and things were more sedate. So, yes, the tractors could start with more traction than a bomber, but once going, they went like shit. The main reason for the limited traction on the class 55 was they had 6x500hp electric motors which was under-rated for the power of the diesel engines (3300hp), so the drivers were told to be careful on startup so they blow the motors apart.
