From Don Mueang, the cheapest and potentially fastest way to get to Hua Lamphong Railway Station is probably by a direct train should the timetable match up with your travel needs. This time, the next departing train was an Express service, however, special fares apply for this short-distance journey, and instead of the official rate of 155 Baht (~$6.36), SRT provides a Third Class special fare for this Express Diesel Railcar service from Don Mueang to Bangkok at only 20 Baht (~$0.82).
Tickets can be purchased from the ticket counter as usual. No need to mention anything about the Third Class special fare for Express Diesel Railcar services, it will automatically be given to you.

The SRT Northern and Northeastern Lines are the cheapest and possibly fastest way to get from Don Mueang Airport to the city. Perhaps you should try this the next time you are visiting Bangkok via Don Mueang Airport.
