Paul Middleton is on the footplate of a North Yorkshire Moors Railway locomotive, travelling between the picturesque stops of Goathland and Levisham. Meanwhile, iconic engine Tornado is brought in on a mission to boost passenger numbers, the lineside team are in action monitoring the UK's only venomous snake, and we see how a Victorian loom is keeping heritage railways all over the world running smoothly.
The steam engine Tornado travels from the remote Levisham station to the market town of Pickering. With the season in full swing, disaster strikes as a giant wildfire jeopardises the steam train services. Volunteers work tirelessly to keep the stations spick and span, and guide dog puppies gaining their first experience of trains.
