There is also a form of respect among writers, usually nices pieces don't get vandalised/overwritten. Hire or just ask actually good writers to make your trains less horrible looking and both parties would be happy. A lot of cities do that nowadays (for walls), at least where I live, and this has been quite a success. I am not saying this will prevent the die hards who like the thrill of going into depots at 3am for a 15min job that most of the time ends up very poorly, but this would probably be more effective and cost way less than drones!
