Aswell as the freight to the sidings, there will be the usual for 2001 MK2/3 Pushpull sets, Mk2 Cross Country, HST, parcels traffic to and from the nearby Parcels depot(off scene), freightliners etc passing on the mainline.
Not looked at the OHLE yet, but suspect I will scratchbuild the structures that will be required.
Cheers
