Strong disagree sorry, many many multiple unit types left un-touched over all sorts of eras, great for "space saving" layouts as well, likewise with modern infrastructure wagons . Lots of low hanging fruit left. There is the claim there is "no new blood" often touted around here yet how much of the real railway today can one realistically purchase in model form? I can't be the only one to think a "simplistic" Electrostar, right shape with head and tail lights but a stripped out interior / dark windows - would be a good money earner?
Rather more on topic, these are great looking vehicles, perhaps slightly crisper than Heljans around the end door hinges - lettering may not have been straight on their sample photographs, I suspect it would have been hand painted originally in real life so perhaps more authentic..
