I was watching television the other night when I cam across this fascinating programme "Railway Walks" in which the presenter goes for ramble down disused railway lines. In that particular episode she walked from Weymouth out to the Isle of Portland* following a line that, whilst carrying passengers, was mainly designed to take the famous Portland stone down to harbour or to the yards for transshipment off to building sites. Portland stone was famously used for St Paul's Cathedral and the Cenotaph, although perhaps this blog should mention it being used in the London Underground HQ at 55 Broadway, London.
This programme was part of a series, but only this current episode is available on iplayer, I think it was a repeat to fill space in the schedule. It would be worth watching if it appears again in the listings.
* The Isle of Portland is connected to the mainland by a spit of land, so the trains don't have to fly!
