I have posted this elsewhere but thought it might be helpful to start a new thread with a clear title.
Accessing Brooklands by Public Transport.
On Friday and Saturday there is a frequent bus service – Route No. 436 – from Weybridge Station to Mercedes Benz World which is adjacent and leaves just a short walk to the Museum entrance. Unfortunately there is no bus service on a Sunday.
If taking a taxi from the Station ask the driver to take you to Campbell Gate (Members' Hill); this is a much shorter journey than to the usual public entrance (i.e. the car park) and about half the price! (Roughly £6 to £8 to Campbell Gate)
If walking you would also arrive at Campbell Gate. From the station, walk south along Brooklands Road (B374) and look for a right turn to JTI (UK). Take that turning (it's a paved road) and carry on down the Members Hill. There is a sign indicating Brooklands Museum straight on down the hill (don't take JTI to the right).
The walk from the station to the Museum is about 20 – 30 minutes.
