HS2 traction power feeding arrangements

[snowball]

How much has been published about proposed feeder station sites for HS2 phases 1, 2a and 2b?

I seem to remember noticing some proposed autotransformer sites on the phase 2b plans but I was concentrating on other aspects at the time.

Is there a list anywhere?

I think autotransformer feeder sites are featured on the phase 1 maps in the government website (although these are 6 years old now and the design will have changed).

This is actually something I've been wondering as well recently; hopefully an answer will be found!
