I always have to smile when I see threads like this, a lot of people seem to think that by bringing up 'the likes of ROG' makes a big route knowledge card something new, I spent 6 years in the 90s with Res/EWS and saw, under EWS, some appalling behaviour in which Management, Railtrack and ASLEF were equally complicit including allowing drivers from a certain London freight depot to sign Willesden PRDC solely by using the sectional appendix, including the wrongly printed platform speed. We had big cards at Willesden, with some drivers signing GW, EC, WC, GA along with loads of yards and depots, and I only recall two mainline SPADs, one by a trainee who was cut and one by a highly experienced driver on a route he'd been driving for years. One thing I do know is that I saw more SPADS after I'd joined a TOC working over fixed routes than I did on FOC work
