I like to know that too, also one for
@Highlandspring and
@jingsmonty but are there any fixed diagrams for the SR HSTs in passenger service and will there be more out in late March?
There are in the Inverness diagrams, but that doesn't guarantee one turning up!
Southbound:
0453 Inverness - Aberdeen (Edinburgh via Aberdeen),
0554 Inverness - Aberdeen,
0944 Inverness - Edinburgh,
1255 Inverness - Edinburgh,
1725 Inverness - Glasgow QS.
Northbound, I'm not that sure, but one is booked to work through from Aberdeen (for 0944 South), the 0950 Perth - Inverness is booked an HST (forms 1255 South) as is the 1710 arrival into Inverness (forms 1725 South). The 2156 Aberdeen - Inverness is an HST (think this works up from the Waverley).
As I said, none of this actually means that an HST will turn up....they've only made very sporadic appearances...
