well i doubt boxcars full of bricks or autoracks with cars are "high threat" but yeah if you love painting oil tankers and intermodals i think your time is up.... i've seen news stories on trains that carry nuclear waste....
if your crew was that great someone else would make a thread for you..this just makes you all look like fame whore toys....oh and stop painting over peoples stuff even if it is old and faded, respect where you come from jeez....
