What are some recods the English trains have set.?

Answer 1

The fastest ever run by a steam locomotive. 126mph by the LNER class A4 'Mallard' in the 1930s. It has never been beaten. Fastest point to point schedule by a regular train service 'The Cheltenham Flyer' from London Paddington to Cheltenham, this during the 1950s. Longest non-stop service, The Flying Scotsman, London King's Cross to Edinburgh, Special tenders with a corridor linking to the coaches were built in order that there could be a crew change en route without the train having to stop. First passenger railway in the world, the Stockton to Darlingtom Railway, 1825. First death of a person killed by a train, William Huskisson MP who stepped in front of a train on the opening day of the Liverpool and Manchester Railway in 1830. First underground or metro service, The Metropolitan Railway in London from Paddington to Farringdon

Answer 2

Can't beat the previous answer except to add that the Deltic Co-Co of 1955 was the most powerful Diesel-electric in the world at the time.
The Beyer-Garratts were the best articulated steam locos in the world, no railway that had Mallets and took on a Garrett ever went back to Mallets. Also the first to crack 100mph with steam, "Flying Scotsman" was it not?
Another was that the non-streamlined steam locos of Britain had the least ancillary bits and pieces bolted to the running boards and boiler sides. They were a lot more elegant. Compare French, German or any US steam loco with a British one of the same era and you will see what I mean.
