I was running through the products list and found that they made new coaches but they are called Red coaches.
The coaches they are referring to are these:

Seen frequently in the show from Season 2- onward.
They're the same coaches Duck almost hits in 'A Close Shave', and the same kind you see him pulling later on in Seasons 3, 4, etc.
I'm really happy Bachmann are doing these. More coaches for engines to pull along the line, and they look good coupled behind any of the engines!
I hope this helps :)
I might just have to buy them
