Back in the day, most railroading was done via timetable/train order. By the early 1990's, these class lights weren't necessary anymore as the private railroad passenger trains were gone and freight trains run by timetable were becoming rare and nonexistent.
White stood for extra, as in any train not regularly scheduled or on the timetable, i.e. a work train.
Green stood for another section of a train following the first section of a train. It was more common on passenger trains than on freight trains. Usually this was done when the first section ran out of car capacity. The last section of the train didn't require green lights. Usually when a train was in the siding for a meet, this was a signal to the train in the siding that there was another following section.
Red usually signified the rear end of a train. This was normally used at night on the rear of a helper set (on diesels) when it was physically possible to see a red flag.
Does that help?
