For london based crew what are the earliest starts latest finishes?
It was mentioned a lot of drivers live in crawley which is an hours commute by train what if the trains are delayed? Whre do most blackfriars and kings cross drivers live?
Is passing out normally within a year or longer?
I am not 100% sure on this but I think the earliest could be something like 04:47 and latest finish is 23:43 (well that's the latest I have finished so far).
I live in Tulse Hill which is 28 mins from St Pancras intl.
I would say give yourself plenty of time to get there. Usually you book on about 15-20 mins before the start of your turn - so you can read all the notices and check everything is in order etc.
Sometimes your turn doesn't actually start at King's cross, it depends - you could start at Finsbury park or something so you head down there and meet your train or sometimes you go and pick up and empty unit from Hornsey depot and head down to Moorgate with it - it all depends on your diagram.
Passing out SHOULD normally be within the 12 months but I have heard of some which have taken 14 months.
