Interesting, are your trips primarily northbound or southbound? The Aberdeen portion hasnt been particularly attractive to me because of the very early arrival at the intermediate Scottish Stations. If Im using the sleeper its better to get the Lowlander to Edinburgh and then get a Scotrail trip. Its difficult for me to see what the business traffic thats using the Aberdeen portion is.Not a scientific study but the Aberdeen portion always seemed to have a lot of business use. It's why I used it (until a combination of higher cabin prices and awful seated accommodation pushed me to the air routes).
