To avoid derailing the Class 313 thread further and to take up my discussion with Class 377/5, here's what the document has to say about Coastway East & West:
The current trains between London Victoria and Littlehampton will continue at the same frequency as now.
The new faster train (the first train to leave Haywards Heath after detachment) will call at Hove, Shoreham By Sea, Worthing then all stations to Littlehampton. Overall this reduces the journey time to Worthing by five minutes.
The slower train (the second train to leave Haywards Heath after detachment) will call at Hove, Portslade, Shoreham by Sea, Lancing, Worthing then all stations to Littlehampton. (page 11)
It is proposed to reduce the journey time between London, Lewes, Eastbourne and Hastings by approximately five minutes through a combination of minor retiming, possible due to the reorganisation of other trains on the main line, and swapping calling patterns. (page 11)
Sample timetable extract (page 20/21):
HHE arr 1259
HHE dep 13:03 13:06
LWS arr ------ 13:24
HOV arr 13:20
Similar on the opposite half-hour. From which I conclude that detachment of Coastways continues at Haywards Heath in the new timetable (and not to do so would require an additional pair of trains which are not shown in the sample timetable).
This, in turn, indicates the use of 377s. Any continued 442s seem to be likely confined to shoulder peak workings.
Unless, that is, the document has been overtaken by events.
