Thomas' Magical Birthday Wishes is the first out of four mini series with fourteen episodes of online videos made to celebrate the 75th anniversary of The Railway Series. It revolves around Thomas using his thirteen magical birthday wishes to help his friends while they set up a surprise birthday party without his knowledge. The shorts are written by Eric Branscum, and the series features the UK voice cast in both dubs as opposed to redubbing the shorts with American actors. The shorts use an animation style that is more cartoony than that of the main series, and feature the voices of John Hasler, Rob Rackstraw, Rachael Miller and Yvonne Grundy. Rackstraw and Miller also substitute the UK voice actors for many of the featured characters. The series will continue with Learning With Thomas.
