Rolling stock question for my second scenario attempt

[amtrake8a]

I scrapped my first attempt for a WCML Over Shap scenario as Armstrong Powerhouse had pretty much covered it in their passenger scenario pack for the same route.

This time I would like to create one for the West Highland South route. This would be a freight scenario - 6E45 the 8:07 from Fort William Alcan to Mossend. I am using the May 2012 working timetable.

I used Google image search to see what rolling stock is used, and it looks like this service uses Class 66 locomotives with several tank wagons (I counted 24 in a YouTube video of this service). I found an image that has a Class 60 hauling the train. http://flickrhivemind.net/Tags/6e45/Interesting

What kind of wagons are used in this service? And secondly, are 66's used solely on this service or could I put in a Class 60 in place (since I would like to have more Class 60 scenarios)?

Thank you for your help.

The wagons are PCA powder tanks and there are some included with the West Highland Line South route. A Class 66 would be the expected power over the line, as there is a pool of these fitted with RETB equipment. I'm not sure if a Class 60 has even visited the West Highlands.

Thank you. I don't know which 66s are in this pool, but I'm making use of the GBRf "Chinook" reskin that comes with the AP Class 66 Pro sound pack.
