Re: Correct Class Light Lens Colors

Just to (hopefully) clear up another possible source of confusion, the word "class" might be easily misconstrued. I am unaware of what was printed in employees' timetables in the States but in Canada, freight trains used to be classified as second class, third class, fourth class or extra. If the employee's timetable carried a schedule for a particular freight train between two points, that train displayed no flags or lighted class signals, no matter what its timetable class. If the freight was operating on a schedule not contained in the current employee's timetable, it was termed an extra, and displayed white flags or lights to the front. The role of green lights/flags has already been explained in a previous post.
