- Use of Audible Track Warning devices (detonators) is discontinued.
Protection for disabled trains, civil engineering works and foggy
weather has been suitably modified.
- References to "air brake" replaced with "continuous automatic brake"
to reflect the diversity of equipment being operated. (e.g. Westinghouse
air, straight air with EP, vacuum).
- Certain expempted rail motors and rail-mounted plant not required to
have a continuous automatic brake.
- Temporary Signals now classified as Absolute Stop Signals. These
(either fixed or Flagmen) are now required at work sites in place of
ATWs.
- Terminology varied as Disc Signals are the only form of Subsidiary
Signal currently in use.
- Additional exception to passing a fixed signal at stop, when entering
a section under Absolute Occupation.
- New White Hand Signal, "visually enhanced" signal to the Guard that sll
is right for a train to depart from the station. Thw white light/flag
option has been deleted from the "all right" hand signal.
