Unable to answer "Is this place wheelchair accessible?" – Pitlochry (Train Station) – https://osm.org/node/6768796291 via StreetComplete_ee 57.2:

All areas are accessible on wheels, but platforms one and two are joined by a bridge that requires climbing stairs.

Moving between platforms without using the bridge requires a not insignificant diversion, leaving the station before entering again from the other side.
