3.
There are four stub and three double ended sidings on this line, one of which, " Best Gate," is a regular meeting point for scheduled cars.
At this siding the switches are set for all cars to take the right hand track and trail through the exit switch. At other double-ended sidings cars proceed at speed on the main line if they have no meets. When- ever possible these double-ended sidings are used for meets with long freight trains.
All schemes for single track automatic signals, prior to th...is installa- tion, employed a preliminary at one or both ends of the block in order to prevent two opposing cars from simultaneously entering a block under clear signals. This, under normal conditions, operates perfectly, but with a deranged schedule may cause either further delay to a car already late or require signal apparatus at the entrance to a preliminary to prevent such delay.
A further study of preliminaries and their eflfects can be secured by a reference to the 191 1 report of this Committee, but it cannot be denied that their elimination is desirable if the substitute does not introduce unsafe or undesirable features.
