In the 1930s Mill Hill East tube station ran through all the way to Edgware tube station with one station called Mill Hill the Hale which didn’t last very long at all. This station was adjacent to Mill Hill Broadway station.
I’ve lived in the area for over 10 years now and I’ve finally walked round and did the first part of the route.
If you come out of Mill Hill East tube station you can walk round and up to see where the track finishes, then you can follow where the line would have gone through. A few bridges aline the route, then you walk between Metro golf course on one side with a football power league centre on the other side. Finally the end of the route terminates into Page Street.
I took some other photos of graffiti but not enough of the route. The are lots of trees on either side. On the other side of Mill Hill there is Lyndhurst Park, from there you can walk all the way through to Edgware to continue the train line route and I would like to walk that next time.
