A day out from Plymouth by boat to the 'Forgotten Corner' of Rame and Cawsand in south east Cornwall was going to be a totally railway free day for me but not so ! A walk along the coastpath to Cremyll took me through Mount Edgcumbe Country Park to catch the ferry across to Stonehouse in Plymouth and there in front of me was a railway albeit 5" gauge and not working. I'd never heard of it but the information display indicated the project started in 2017 and there has been running in 2018-19. The link I have included states that they intend to re-open on July 4th on Sundays and Thursdays until September but with no passengers allowed while pandemic restrictions apply.
Bus 34 from Plymouth Town Centre will take you to Admiral's Hard where the ferry across the river will land you at Cremyll. If you are driving up from Cornwall turn right at Trerulefoot.
The historic Royal William Yard with an abundance of food and drink venues is next to the ferry quay and an excellent lunch or afternoon tea can be had at the Orangery Garden Cafe at Mount Edgcumbe House. Another one for Roger to put on his 'to do' list.
