On the just before 8am bulletin they mentioned the use of emergency brakes and that around 150 passengers were on board.
So, a safety system (the Mk1 eyeball and emergency braking system on the unit) was operated as designed and worked successfully to avoid a collision.
One thing that's more worthy of discussion (for the future at least) than the RMT's DOO argument is how that kind of incident could be safely mitigated if the train had been self-driving with only a guard on board. A trip wire on the OHLE gantries may well have worked, to use one possibility (and one that is already deployed on the Manchester Airport spur).
