At work we have many people coming up for meetings or courses in Inverness from all over Scotland, Aberdeen is not a problem as the timings for this service is reasonable considering the prehistoric nature of the infrastructure. But coming from anywhere else, Perth, Stirling, Glasgow, Edinburgh, Dundee, they don't arrive until 11:00 at work (with first arival at approx 1030). Now I know it's more a rolling stock issue but we deffinatly need a more intercity version of train particullarly for busy business based trains, I could go into to more detail, but it would not be infrastructure related.
What is an infrastructure related issue on the HML, which decreases capacity, is that its only open 0600 to 2355.
