In late October, some friends and I will be travelling on the 08:10 departure from Perth to Inverness. We've been allocated seats in coach A - 21B, 21F and 22B. I want to make the most of the views on the Highland Main Line, so I'm trying to work out which side of the train this is on (so I can book our return journey on the Highland Chieftain on the opposite side). Thing is, I've been given conflicting information by the unofficial seating plan I've obtained online, and the uncertain employee at the Scotrail helpline. Can anybody in-the-know shed any light on this - will we be sitting on right (east) or left (west) side of the train heading North?
