On July 3, 1938, Mallard billowed out smoke as it reached speeds of 126 mph – a little over 200 kmph. With that, Mallard became the world's fastest steam locomotive, a record that it holds till this day.
Certainly. One highspeed “light” train -meaning a single passenger coach, one baggage car, and dining/bar car - averaged about 45 MPH but one section of the run where the track was straight for many miles it would run 90 MPH and was timed at 96 on a few occasions.
On 30 November 1934 his Flying Scotsman, an A1 Pacific, was the first steam locomotive to officially exceed 100mph in passenger service, a speed exceeded by the A4 Mallard on 3 July 1938 at 126mph, a record that still stands.
In 1934, The Flying Scotsman became the first locomotive to achieve a speed of 100 miles per hour and dramatically reduced the journey time between the two capitals. The end of her career on the East Coast mainline in 1963 was not the end of her story though.
Faster inter-city trains: 1920–1941Rail transportation was not high-speed by modern standards but inter-city travel often averaged speeds between 40 and 65 miles per hour (64 and 105 km/h).
The Glacier Express is the world's slowest train, taking more than eight hours to travel between Zermatt and St. Moritz in Switzerland at an average of 18mph. Along the way, it passes over nearly 300 bridges, travels through 91 tunnels and takes in endless stunning Alpine views.
In 1928, the LNER decided to make The Flying Scotsman a non-stop service for the first time and 4472 was one of five A1s selected for the service. It hauled the inaugural train on 1 May, completing the journey of 392 miles (631 km) in 8 hours and 3 minutes.
Scotsman, now numbered 60103, was painted blue for a time, then BR Green. Flying Scotsman at Doncaster Works in 1957, numbered 60103. It remained this colour until 1963, when it was retired by British Rail.
