The Railway Series
Welsh was the first - and for many years only - translation of The Railway Series books. In 1950, Welsh minister Sir Ben Bowen Thomas suggested that Edmund Ward publish the engines' adventures in the Welsh language. As a result, J.T. Jones, a former winner of two National Eisteddfod literary awards, was paid seven guineas to translate the first four titles - Y Tri Injian Tren, Thomas yr Injian Danc, James yr Injian Coch and Thomas Injian-Danc Eto - each of which were produced in a print-run of 5,000 volumes.
- Only the first seven series along with the thirteenth and fourteenth and Hero of the Rails were dubbed.
- Old Iron, Thomas and Trevor, Percy Takes the Plunge, Pop Goes the Diesel, Better Late Than Never, Break Van, The Diseasel and Wrong Road were not put on Home-Media, but were aired on Slot Meithrin.
- Paint Pots and Queens, Horrid Lorry, A Better View for Gordon, Lady Hatt's Birthday Party, Baa!, Toby and the Flood, Haunted Henry, Thomas and the Rumours, Sir Topham Hatt's Holiday, Make Someone Happy and Duncan Gets Spooked were also seemingly not put on Home-Media, though they could have been dubbed.
- Jack Frost, What's the Matter with Henry?, Rheneas and the Roller Coaster and Not So Hasty Puddings were never given home video releases, though they were dubbed and aired on Cyw.
- The first eight episodes of the fourteenth series used the thirteenth series's version of the Engine Roll Call.
- Unusually, the Welsh dub is one of the few known versions of the show to translate most of the signs within the episode.
