No, I'm just talking about implementing on the inner suburban area where station dwell times are critical to providing an intensive service. All doors opening has been implemented on Thameslink for ages now and I'm not aware of issues with bikes falling on to platforms or passengers thinking that doors will open automatically at Wivelsfield.
Thameslink doesn't just serve inner suburban. I would have assumed dwell times are a problem outside of the inner surbaban too but perhaps not. I mean during parts of the morning there are 22 trains through Clapham Junction on the fast lines. Whilst these trains don't stop there, they do stop elsewhere and would surely need to be on time through Clapham Junction to avoid delays to other services.
Also fast trains mostly use platform 1 at Surbtion and that is used by stopping trains. Dwell on a fast train, e. g. train from Alton to Waterloo, could affect a stopping train, suchas Guildford to Waterloo. Those are often late departing Surbtion as there is only a three minute gap between services.
If any or all of those trains do not have automatic door opening then they can delay other trains.
I'm not actually adverse to the driver opening the doors. My issue is ensuring there is a guard on all trains who is fully safety trained. However if we are looking at drivers to save time with doors then surely they also need to look at passengers.
