Trying to identify a couple of Inverness freight services

[JohnMcL7]

I'm not sure if I should be asking in the TOPS thread or separately, I'm not looking for the exact locomotives but just wondering what these two services are likely to be:

Aberdeen to Dalwhinnie seems an unusual route also I notice it's scheduled to stop at Culloden for nearly an hour, is that right beside the viaduct?

Thanks for any help, I'm trying to find anything more interesting than the usual passenger trains passing through up her.

6T44 1354 Aberdeen Craiginches to Dalwhinnie Siding will be DR73915, a Plasser & Theurer 08-16/4x4C-RT Switch & Crossing tamper.

6J98 1940 Aberdeen Craiginches - Inverness Colas will be DR77001 which is the Plasser & Theurer AFM 2000RT Automatic Finishing Machine.
