Whilst capturing footage of the Corsehill Castle ruins near Stewarton, a ScotRail service Class 156 rolled by. Managed to rotate my camera around in time.
Filmed on: DJI Mini 3 Pro
CAA registered.
NOTE: Due to the DJI Mini 3 Pro being under 250g, CAA restrictions for 150m near railway infrastructure do not apply. I was flying at an altitude of 57m away from the railway.
