The colors won't match because the original paint on the boxcar is old and faded, but the new panels and stencils are new paint. The railroads really don't care that much about freight car as long as they do the job and mandated reporting marks, etc. are clearly visible. At the rail seminar I attended at work a couple of years ago, one of the guys asked the rep from BNSF how often they washed freight cars. His response was the inside is washed on a reefer as often as needed to keep the car clean for transport of food items. The outside is never washed unless the car needs repair. Freight cars are there to make money not look good. The biggest concern the railroads have with that kind of vandelism is that being around trains is dangerous. The railroad industry has one of the highest mortality rates of any industry, and that is from mistakes by trained people. They would really rather not have vandals killed on railroad property. The other problem if course is when vandals cover up required stenciled information, the railroad has to pay someone to repaint a panel and restencil before they can use the car again.
