Do you mean that the ticket with code 500 plus one small and two large includes a ride on Heavenly Creation?

The Two Big One Small (两大一小) train package from Beijing to Baotou/Hohhot includes the Sky Train (天空一号), which is a high-speed train section on this route. So, yes, tickets with codes such as 2A1X or similar would include the experience of riding the Sky Train.
