Aldochlay

 was the location of a transmat substation in Scotland in the 162nd century. It was intended to be the router for all of Europe, for when future Nerva City colonies spread across the planet. Four kilometres from Inchfad Isle, Aldochlay was located on, or very near to, Loch Lomond.

The Sixth Doctor and Flip Jackson visited Aldochlay in 16127, the latter after crashing a microlite nearby. (AUDIO: Wirrn Isle)
