LNER A4 Class 4464 (60019) “Bittern” has been given dispensation to run at 90MPH on the East Coast Main Line in July, to celebrate the 75th Anniversary of Mallard’s world speed record, subject to a satisfactory high speed test. This is that test. The weather was perfect — damp, cool, no wind. Bittern left Didcot at 05:23 am and flew through Slough 05:58 at full pelt for an average of 60mph over the 35 miles. The 6.2 mile section between Maidenhead and Slough was completed in 4 minutes, an average of 93MPH. Using film time markers I timed the whole train at 90mph through Taplow where this film was shot.
Given the two sets of hand cranked data, and with no speed gun to hand, I am happy to put the 90MPH stamp on the film title.
