Got the numbers slightly wrong yesterday but the right gist - the September permanent gives us 13 3 car and 3 2 car units.
4 are on the Marshlink, as Louis mentioned they are on a 4 day rotation with one unit spare on St Leonards all day with just a single ECS to Eastbourne.
on the Uckfield peaks to London
0531 8 car
0633 8 car
0703 9 car
0833 8 car
0933 8 car
From London Bridge PM peak
1607 8 car
1707 8 car
1807 8 car
1907 8 car
Off peak is an hourly 3 car.
Well you'd like to think that the fleet specialists that maintain these day in day out know what they are talking about - it's definitely the plan (although there is still 3 weeks to change their minds
)
