90 trains, but 750 carriages according to that. So they're going to be long trains. The current 455, 456, 458 and 707 fleet add up to 742 carriages by my sums. There's also talk of a consistent metro fleet. I reckon they could all be replaced.
That has been the plan from the get go either 5 car or 10 cars.
