I worked at South Tottenham signal box in 1984 , one day the signalman next door at Harringay Park Junction phoned me to say 'That's it , I've locked the points in reverse and chucked the signal box key in a bush , I'm on strike in support of Arthur Scargill and the miners ' He stopped the job for around 2 hours if I remember rightly , kept his job though !
Nope, same manufacturer but different type of engine. Class 56 low revving 127 litre V16 ( 900 rpm ) 3200hp . Valenta in HST hi revving (1500rpm) 79 litres V12 2250 hp. It's the turbo whistle that you can hear that makes them sound similar, at full rev's under load completely different sound. Look on YT for video of Valenta HST and class 56 and you'll hear.
@@jabberwockytdi8901 56's are 246-litre cubic capacity. The engines roots originated from LMS prototypes 10000 and 10001, through to Class 40, Class 50 and then in its penultimate development in the Class 56. Class 50, 50009 was withdrawn equipped with an engine block from a Class 56. English Electric bought Paxman Diesels in 1966 which then became Ruston- Paxman who went on to develop the powerunit. A quote from the Wiki page: The engine and electrical systems were new. The engine is a single Ruston-Paxman-built power unit, the final development of the English Electric CSVT engine, following on from the 16CSVT used in the Class 50".
Absolutely fantastic footage. Brought back so many memories of how everywhere used to look. Thanks.
I was on that tour. If you had turned the camera to face the other way you’d probably see my youthful self leaning out the window smiling away 🤪
Hellfire! Lot of my local lines here from back in the day before they became a linear forest.
