What is the name of the author who continued The Railway Series after Rev. W. Awdry?

The author who continued The Railway Series after Rev. W. Awdry was Christopher Awdry.

Rev. Wilbert Awdry created the series, beginning with The Three Railway Engines in 1945. He wrote 26 main books before retiring after Tramway Engines, published in 1972. The stories feature anthropomorphic locomotives working on the fictional Island of Sodor, with Thomas eventually becoming the best-known character.

After an 11-year gap, Christopher Awdry began the next phase of the series with Really Useful Engines in 1983. He wrote 16 books in total, including James and the Diesel Engines, Great Little Engines and Thomas and Victoria. His final Railway Series book was Thomas and His Friends, published in 2011.

A common mix-up is confusing Christopher with Richard Awdry, Christopher’s son. Richard has discussed and appeared in Thomas-related events, but Christopher—not Richard—was the writer who directly continued the original book series after his father.
