The 1972 stock is bright blue. It should be different shades of blue The ICE wheels are clipping the railhead, and the sleeps sit too high, they should be lower down in the ballast The seating next to the Sherlock mosiac should be black and yellow, as it's the standard colour of underground furniture
These are rather just bad designs than game bugs, but I get your point. As for the ICE wheels clipping the rails, isn't that something that for some reason always happens on promo-shots?
