PRR also covered car movement and/or placement in the individual Employee Time Tables, since so many operations were unique. Example topics included: limitations to certain power classes, cars to be separated by spacers (MTYS) on certain tracks or bridges, movements accompanied by flagmen or lanterns, forbidden "open flames" with certain properties (directed at brakemen), trestle tonnage and car limitations, and the like.

cars, but it is unclear if they also added any rules concerning
placement in the train, beyond the "not adjacent to locomotive,
caboose or occupied passenger cars" already enforced for cars
containing explosives. Tony Thompson has a nice summary of the
placard rules from a modeling perspective in his blog here:
