WE'VE comprehensively covered the first 18 EDAs with the Doctor and Sam... but we don't want to stop there!

There's still a few stories featuring this pair to be covered, before Fitz arrives, so we're turning our eye to the world of Short Trips. We've previously covered Bounty, Dead Time and The People's Temple, and since we're completists, it would be wrong not to do their other adventures, published in the BBC Short Trips books.

Today, we've got Steve Cole telling us about Model Train Set, as well as a chat with its author, Jonathan Blum.
