Thomas track sets..? Help needed.

[ImHereForTheEntertainment]

My teen used to have Take Along Thomas which was the little die cast trains and grey track
He had the motorised ones too with blue track I can't remember the name of that

Unfortunately and stupidly I got rid of it all

I now have a baby and I'd like to start collecting again the die cast style but it's all changed names.
What is it I need.?

Blue track was the old style trackmaster. The trains have rubber band type tyres whereas the new style trackmaster have notched wheels. Most are compatible apart from when building steep hills.

Take along became take and play which are essentially the same but lower build quality.

Before it was trackmaster it was called road and rail or something. That's what he had. I remember it changing when he was starting to grow out of it.
I preferred the take along stuff as liked the die cast trains.
Think I need to wait till smyths opens to go and start collecting so hard looking online.
Thanks for your help.

Love the idea of being compatible too.
