Should have done my homework

Went out for a walk this afternoon - the weather was wonderful and my head was full so it seemed appropriate. I decided to grab a shot of this building because it's called "Old station house" and it's on Beeching Way which is the road built on the route of one of the old railway lines to East Grinstead. As I took the shot I was thinking about how I'd identify which of East Grinstead's stations this had been but I've failed big style. I'm thinking that it's probably the original 1855 station building but I may be completely wrong.
