Does anyone remember train shaped toaster pastries with a little sachet of icing?

Been thinking about this for a long time. I can't remember much about them, I was just a kid. But I'm sure they were train shaped, possibly like doughnuts... if I remember correctly, you would put them in the toaster to heat them up, and they came with a little sachet of icing to put over them. I'm sure I haven't made this up but no-one I know can remember them!
