I could be wrong but I always thought that Plarail was the only maker of the motorized Chuggingtons and it doesn't look like they have released anything new in a very long time. As Sunhuntin has Posted above, checking the Links at Hobby Search you should find all that there is...or, at least, close to it. Someone else may have more updated info on this line.
