Platform 1 being 12-car is sufficient for a couple of morning services
to London to be 12-car, and, from next month, a couple of evening
services back from KX as well.



Maybe that's been substituted by the island, or is that a completely
separate exercise?

I don't know. My understanding is that the island platform is needed
to support 12-car trains to Liverpool Street (which, as Jim C says,
are already being built).

Although 12cars Cambridge Liverpool Street is also not a completely
new idea - there used to be SX peaks 12 cars 317s tats exactly why
Bishops Stortford et al got platform extensions.

OK it was an extremely limited operation, maybe it was even only one
train each way each peak, but it did happen.
