The first four seasons have been reprieved from the wilderness and are available for streaming on the payable service.
The 13th and 14th seasons follow suite, as are specials Calling All Engines! and The Great Discovery.
It comes after a large cull of titles, including Thomas, hit the media during May 2013.
Another removal, more specifically of Lionsgate's US DVDs, occurred almost a year after.
Thanks to Hawk01 for the alert.
