Helen Mark takes a ride on the new Welsh Highland Railway, which eaves Caernarfon and takes in the stunning Snowdonian landscape, before arriving at its destination in Porthmadog. Along the way Helen hears about the back-breaking work undertaken by hundreds of volunteers to get the railway up and running and about the history of slate mining in the area, which used to rely so heavily on the railways. She also stops off at the RSPB's Osprey Project at Glaslyn to catch sight of the only breeding pair of ospreys in Wales.
