middle siding signals

[NW Mailing List]

A “G” plate is not compatible with Stop & Stay. The “G” turned a Stop & Proceed into Restricting - it just eliminated the need to stop before proceeding. Usually used when climbing hills (grades - hence the “G” and the term “Grade Signal”) where the thinking was stopping and then the risk of breaking the train in two was greater than the risk of not stopping before entering the potentially occupied block.

While Stop & Stay signals could be capable of displaying Restricting (see the Call-On signal topic), it was done under dispatcher/operator control. Grade signals with their G plate had Restricting as their most restrictive signal.
