Roundhouse Bertie Part 2 - Steaming Up

In this second part of the beginners' guide, I raise steam on Bertie and run him - first on blocks, then on a rolling road and finally on the Summerlands Light Railway. As I just ramble on in the film, I have added clarifications where necessary at the bottom of the screen. Please note that i have no connection with Roundhouse, other than as a satisfied customer.
