Is there a minivan route (probably from Victory Monument) that stops at Don Mueang train station (directly opposite the airport) during the day?

Perhaps one from Morchit or Victory Monument station that goes to Future Park and stops there along the way?

Shuttle bus A1 from morchit bts direct to airport. Exit 3 walk towards airport you will see the sign.

Oops. Just saw you were looking for the train station. Can walk across bridge.
