Cartoon Network is a Satellite television channel owned by Turner Entertainment that aired Thomas & Friends in the United Kingdom on an early morning timeslot from 1995 until 2001. The fourth and fifth seasons premiered on this channel.

Each broadcast consisted of three episodes from the first four seasons in a random shuffle; Season 5 joined the slot in 1998. It also airs Thomas and Friends in Japan as of today, as well as Pingu, another HiT Entertainment owned production in both Latin America and the United States from 1996-2001 (2006 in Latin America).
