Certainly used to work a lot more freight than they do now...
have worked at least the following regularly at some stage on Southern WCML, plus more i'm sure i've forgotten about.
Cars
Intermodals
BOC tanks
Speedlink/Enterprise general workings
Parcelforce pocket wagons (loco off van duty)
Introduction (much delayed) of 92s took up a lot of the freight workings. This coupled with EWS coming in and reorganising pools saw skodas used on less freight and more van trains (previously just 016-020 RES sponsored)
Basically been out on West Coast passenger duties since introduction until December 05, scottish sleepers since 97. Plus GNER workings...
Still have a daily Wembley-Garston and return car train and occasionally appear on enterprises down here, often in multiple.
