Couldn't find any images (not even on Sun's site), but I seem to recall an early RC Shinkansen with dark blue. Could be wrong, though.
In early 2011, there were no "punched" wheels because the packaging sticks weren't being used yet, and Fisher Price still made two wheel types without holes for rods (spoked and flat). As such, the first batch of Day of the Diesels releases didn't have either.
