St Pancras International Platform Offsets - UIC GC?

[BogiePicker]

Anyone know the platform offsets for St Pancras Intl (& Stratford International International platforms, also Ashford and Ebbsfleet Intl).

Obviously they take a 374, much wider not only in the main body but in the lower sector than UK stock. By eyeballing them from videos, it doesn't seem that they can take full 3.15m wide GC stock, which are wider than the 2.9m Velaro by about 20cm.

They are of course at considerable vertical and horizontal remove from a 373's doors; by visual inspection from videos, the 374, built for vertically lower Continental platforms, fits them rather better.

The international/Eurostar and Kent/domestic/Southeastern platforms are built to entirely different standards, with the latter following standard UK platforms for both height and offset.

The HS1 network statement states that HS1 is UIC GC, with the exception of domestic platforms (which are UK standard), lines connecting to the domestic network, and the Ashford International Eurostar platforms (which are UIC GB). It's in section 3.3.2.1 from the network statement available on the StPHS website.
