20. Kinds of fixed stop signals for departing trains.
(1)The stop signal which control the movement of trains leaving a station are of two kinds, namely-(i)starter; and(ii)advanced starter.(2)When a train leaving a station is guided by only one starting signal, as in case of a station having either only one departure line or having a common starter for two or more departure lines, it is the last stop signal of the station and is called the starter.(3)When a train leaving a station is guided by more than one starting signal, as in case of a station having two or more departure lines each provided with their own starter signal, the outermost starting signal is the last stop signal of the station and is called the advanced starter.(4)The starter, where only one such signal is provided, or the advanced starter shall be fixed at an adequate distance of not less than one hundred twenty meters outside all connections to which it refers and defining beginning of the block section, beyond which no train shall pass, without authority to proceed required under the system of working.(5)The starter which refers to only a specific line shall be placed so as to protect the first facing points or fouling mark of the connections to another running line.(6)(a)When in addition to advanced starter and the first starting signal referring to a line, additional starting signals are provided due to divergence of running lines before entry into a block section, the first starting signal shall be called starter signal and the subsequent signal shall be called first intermediate starter signal, second intermediate starter signal and so on.(b)In case of stations having extended loops provided with more than one starting signal, one after another, the last starting signal shall be called the starter signal and the preceding starting signal shall be called the rear starter; and in case more than one rear starters are provided, the starting signal immediately preceding the starter signal shall be called the first rear starter signal, and the signal preceding thereafter, the second rear starter and so on.(7)Whenever there is a need to indicate to the loco pilot which one of the two or more diverging routes is set for him, a route indicator, as described in sub-rule (3), (4) and (5) of the rule 19, shall be provided on the post of the starter or intermediate starter signal.(8)"Every starter signal or intermediate starter signal, protecting a line used for berthing of trains, shall have a board fixed on the signal post indicating clear standing length in meters written in white against a blue background. Where the clear standing length cannot be indicated on the signal post, a separate indicator board shall be provided.
