Tony,
I think 60002 is on the 11:00 KX-Glasgow. The 11 coach set matches very closely the Winter 1959 formation (don't have access to a summer 1959). The RK is possibly a substitution for a non-available RF. The leading BSK & CK would be for Aberdeen.
60012 could possibly be the 10:00 SuO KX-Edinburgh. The front 5 vehicle types (BSK, CK, SO RF, FK) match in the summer 1958 ECML CWN, although none are shown as Mk1, so maybe a year or two later than that.
