A few more mapping requests for Trainz:
Could you please add a statue on the map, in the corner in front of the door to #15, facing the long corridor. Also, #20 should have a shrine (altar icon would work) in the middle, let's say on the boundary between the square marked "20" and the one below that (hope that's possible using ID). You may also want to add some various furniture along the north and south walls of that room. Or just use the "rubble" icon, since that's what it'll be if there's a decent fight in there... the furniture is very brittle.
