Salty's Secret Story
Oliver and the Slip Coaches is the fourteenth episode of the first season.
Summer time was a busy time of the year on the Island of Sodor because this year, there were many holidaymakers visiting from the Mainland to see the island's many coastal lines. They often visited the beaches, mainly the beach at Bluff's Cove, which is on The Little Western Branchline. Because of this, Duck and Oliver are always kept taking passengers to and from the beach. It is very exhausting for the two engines, but they are still able to manage regardless of the heat. Duck never really has to complain since he pulls his own selection of Slip Coaches, which are coaches that can be uncoupled at stations without having to stop.
