So this could be one of two stations, Westwyvern, or Westercoast.
In favor of Westwyvern:
I think that Westwyvern is much more likely.
The poles show that the station is most likely operated by express, also notice how the numbering on the platform signs is wrong. This could just be an error, but it could also be the terminating platform at Westwyvern, as it connects to platform 2.
In favor of Westercoast:
This could be Westercoast, with the addition of an express platform.
You can kind of see where the viaduct is in the background, and the speed change next to the class 66 reflects the speed change when entering the Westercoast tunnels.
The Class 66 locomotive is sitting on what looks to be a siding, this could mean we are getting a new siding at either of the stations.
