Hello Ras,
Cost could be a limiting factor but it all depends on how much the track is and what is available. I could stick with RC track based on the chances of me getting an old electric loco being very slim, it just depends. The one limiting factor at the moment is not track or anything else like that, it is being able to get hold of suitable waggons, wheels, bogie's and chassis for my 'train' as some of the Playmobil stuff has dried up outside Ebay. Track and a suitable locomotive is just a bonus at the moment as weird as that might sound

. I would get more fun out of making special waggons and rolling stock in anticipation of the new freight locomotive.
As for the old works train I am after any pictures showing its unique details and possibly 4 pictures would do it (with a Klicky for scale). One of the cab interior, a front shot, side shot and one showing a close up of the chassis and wheels or how the body fits to them. I am not fussy really, I would just love to see the cab interior if that was all I could get !
