Lurker here, and sorry if it is not helpful but I found some special Thomas and Friends episodes on Netfilx, but I'm in Canada...so not sure if you can get them in US.
There are Thomas movies on Hulu. I was so mad they took them off the PBS app!
Yes me too! When I was sick I could lay with my youngest in my bed with me and let her pick from the pbs app - knowing that nothing inappropriate was in there. 😔 she was so upset this am that there were no trains!
