Thanks!
Are there any regular freight workings anywhere at the moment whcih reliably produce a 68?
As per ABB's reply above, most of the nuclear flask trains (with the notable exception
of the Georgemas working) are booked for pairs of class 68s, although a class 88 can
sometimes deputise for one of the 68s.
Other than that, the Grangemouth to Aberdeen and Mossend to Inverness intermodal
services are usually 68-hauled, with the Inverness loco also working from Mossend to
Tees Dock and return on a Sunday.
