IT'S full steam ahead for the second series of the TV show following the comings and goings on the North Yorkshire Moors Railway.

The first episode of Yorkshire Steam Railway: All Aboard, which goes behind the scenes, meeting the staff and volunteers that keep the railway on track, starts this Friday.

Last March, the programme reached more than 3.5m viewers across three episodes.

This new six-part series sees the railway addressing the challenges of keeping trains operating during a heatwave in peak timetable season, while locomotive 5428 Eric Treacy makes a return to traffic and engine shed manager, Piglet, visits Erica the cat, which retired after 15 years of service.

Also highlighted are three of the railway's most popular events: the annual steam gala, the Railway in Wartime event and the Halloween train - all of which attract thousands of passengers to the line.

Yorkshire Steam Railway: All Aboard is on Channel 5 on Friday, May 17 at 8pm.
