The Mail Train/Post Train is a night train that delivers letters and parcels to destinations around Sodor. It is only used on the North West Railway. Thomas pulls one train along the his branch line, Percy pulls a train on The Main Line and Oliver pulls one along The Little Western.
Two seperate post trains first appeared in the episode, Night Run which were taken by Thomas and Percy. James was not happy to take the post train and run on branch lines. After breaking his tender coupling, James had to be abandoned on a siding while both Duck and Oliver took the post train for him back to the harbour. After James gets reprimanded by the Fat Controller, Oliver was chosen to take the post train to give parcels to every station on the Little Western. In Christmas Delivery, Oliver took the post train from the harbor along with a sailor named Richard to meet his wife Susan at Callan station after helping James out of a snowdrift.
The GWR 14xx tank engine knew he was late for the Fat Controller's Christmas party at Knapford Sheds. During season four, Bear helped in taking the post train and James hauled the train at Crovan's Gate when the Hymek diesel had his injector frozen up after destroying a snowdrift at Henry's Tunnel. From 2009, Sheffield was seen taking the post train at Knapford during the special, Winds of Change. The post train made a cameo appearance at Ffarquhar Sheds during the sixth episode, Doncaster Drawn.
In 2011, postal traffic on the NWR declined sharply. With the advent of email and texting, physical post wasn't being sent as much anymore. Therefore, in Percy's Post, the Fat Controller made the decision to discontinue dedicated post trains and instead run a single mail van passenger trains. This meant Percy didn't have to wake up as early as before, which threw off his sleep schedule greatly.
The post train is based on the general utility vans from British and Southern Railways. These vans were previously known as covered carriage trucks.
