7x4 - Thomas & Friends

Skarloey is crossing an old bridge when he notices the track is out of place and can't stop in time, thus leaving him dangling above the river from a long way up. Rheneas comes and rescues him with the breakdown train and the bridge is soon repaired. But Skarloey is terrifed of using the bridge again and has to shunt trucks and coaches in the yard. Rheneas has to do Skarloey's work now as well as his own. But when he runs out of water due to puffing too hard, he ends up stopping over the first quarter of the bridge and now Skarloey has to overcome his fear and must cross the bridge to save him...
