The beading won't survive the sanding required to get a smooth surface on WSF. OK, the trams were rough, but that was dents and dirt. not lack of detail. I agree with the stuff about scartchaid and not killing modelling, and respect your opinion to model however you see fit, but I won't be redrawing this one to print in WSF.
But I do think plenty tram modellers like detail, they tell me so when seeing my prints. Gauge on trams being underscale is a plus for most modellers too, many early trams were only 6 foot wide and there just isn't room for wider gauge/wheels unless you go finescale.
