Scotrail Loco Hauled enq.

[postye]

I'm planning a Central Scotland rover in a couple of weeks time and wondered what the situation with the LHCS on the fife circle is.
Do the class 67's on the fife & sleepers swap around often or is it likely to be the same loco each day?

Thanks

The 0736 Cardenden - Edinburgh (normally booked a 67) was a 2 car 158 on Thursday.

Looks like they have more leeway with DMU diagrams now that the Whifflet and Cumbernauld lines are electrified.
