Anyone Like Railways And Model Railways?

I spent quite a lot of my younger life in Swanage and often used the steam railway. One of my interests is disused Underground Stations, I love how some are just frozen in time. I am planning on going to from London to Scotland on a sleeper train, the new ones are en-suite.

What is this +1 or -1  near the reply button do? May have put -1 in the past as wasn't wearing my reading glasses! Assume it is a "Like?"
