The book on the right was issued in 1923 and is a fascinating read on how the "department" wanted their drivers to operate the train.
I have just obtained an almost complete set of VR track charts from 1929, apart from showing gradient information they also show track layouts for the entire state! Pages that contain a track chart in addition to the diagram from the grades book are identified by a "TC"
