Thanks. What determines the decision on whether a particular train will be driven by a driver or run as ATO?
Principally if the driver has been trained or not. If they are trained in ETCS they have to use it, as it is the highest level of safety protection available. There are certain conditions that have to be met to use ATO, but generally drivers will use it if they have been trained to (why wouldn’t you).
Are there drivers who are not trained in ETCS driving through the core?
Yes, lots, although the number reduces every week.
Do they act in uniform? I was in Munich the other week and the inspectors on the U-bahn do their checks in casual clothes to avoid people recognising them and leaving the train.
Munich inspectors were doign that @ third of a century ago and I suspect long before that!
TL RPIs have been known to be in ‘mufti’, but usually they are in uniform.
Like 4 SUB and 4EPB units used to when being driven.
Oh look, class 700 trains have clasp brakes (like 4SUBs and 4EPBs) as well as disc brakes.
If the 700s only had disc brakes (as per virtually every other train built since 1980) then such ATO operation in wet/leaf fall/icy weather would be very entertaining and keep RAIB in work.
Last time I looked (or indeed anytime for the last 20 years) there wasn’t much in the way of ice or leaves between the north portal of Kings Cross tunnel and London Bridge.
Nevertheless there are still examples of the ATO misbehaving, albeit not due to adhesion and not in an unsafe manner. Drivers are not held responsible for such incidents.
