East Coast 801 uses emergency rescue mode - Posted: August 4, 2020 - 7:33 PM Quote and reply
On the 27th July a member was on the 1703 Kings Cross to Leeds when it was held at Retford due to Overhead Line Problems which were not fixed for around a further 4 hours.
The two 5 car class 801/1s each have one diesel engine and these were fired up producing a speed of 73 mph on the level, dropping to 66 over Pipers Wood and increasing to 82 on the descent before sigs intervened. Not bad at all!

Modelling this performance, I estimate the balancing speed of 5-car 'electric' Azumas in standby diesel mode to be around 80 mph (although of course it may take sometime to reach this unless there is a gradient gravitational 'kick' along the way).
In standby diesel mode , full length 9-car 'electric' Azumas have both a lower power-to-weight ratio and increased auxiliaries to supply and I predict a balancing speed closer to 60 mph. Hence would expect a lot of running in the speed range 50-60 mph (which is still a useful capability to have).
