Study Notes
Repeating Signal Types
- Repeating signals are marked with an ‘R’ and can be a banner type, semaphore arm, or colour light signal.
- Banner type repeating signals in Two-Aspect Signalling show:
- On Position: Indicates signal is "on".
- Off Position: Indicates signal is "off".
- Semaphore arm type repeating signals provide similar indications as the banner type.
Colour Light Signal Indications
- Colour light type repeating signals also show:
- On Position: Indicates signal is "on".
- Off Position: Indicates signal is "off".
Signal Visibility and Protocols
- A repeating signal must be provided at a suitable distance from an obstructed Stop signal.
- Repeating signals are not considered Stop signals; they can be bypassed with caution.
- Banner type repeating signals are not illuminated at night.
Reporting and Maintenance
- If a locomotive pilot observes a defective repeating signal, they must report it in writing to the Station Master of the next scheduled stop.
Starter Indicators
- Starter indicators repeat the aspect of the starter signal to assist the guard in determining the status.
- Indicators show no light when the starter signal is "on" and yellow light when "off".
Fixed Signal Requirements
- Fixed signals must default to the most restrictive indication in case of failure.
- There are specific conditions for taking signals "off" based on train approaches.
Signal Equipment for Different Classes
- Minimum signal equipment varies by station class:
- Class B: Distant, Home, Warner below Main Home, Starter.
- Class C: Distant and Home signals.
- Additional signals are mandated based on operational needs.
Shunt Signals
- Shunt signals control shunting movements and can be a white disc with a red bar, or position light signals.
- More than one shunt signal may coexist on a post, with specific authority levels linked to their indications.
General Maintenance Protocols
- Station Masters ensure signals are operational, lamps are clean, and lights are visible during night operations.
- Signal lamps must be inspected regularly for cleanliness, focusing, and defects.
Training and Responsibility
- Operating staff are tasked with the upkeep of signal cleanliness and operations.
- Station Masters are responsible for instructing staff on protocols and conducting inspections.
Emergency Protocols
- In emergencies, signals can be repositioned under controlled communication to avert accidents.
- Shunt signals must provide clear instructions for safe shunting operations, ensuring appropriate precautions are met for all signal positions.
Inspection and Oversight
- Signal Inspectors conduct regular inspections to ensure proper functioning and cleanliness of all signal lights and parts.
- Yearly overhauls and prompt reporting of defects are essential for operational safety.### Burners Maintenance
- Burners gummed with oil, soot, or incrustations require periodic chemical cleaning by S & T staff.
- Broken or defective burners must be promptly reported to the Signal Inspector for replacement.
Wicks Maintenance
- Wicks should be trimmed daily, removing the charred portions to keep them clean and even.
- Wicks that are too short or clogged must be replaced by S & T staff with clean, dry wicks saturated in oil before use.
Lighting of Lamps
- Utilize assigned matches for lighting founts and avoid using oil waste.
- The wick must be adjusted for a steady burn without smoking; too high a flame causes smoke while too low causes focus issues with the lens.
- Ensure lamps and wicks are protected from water, especially during the monsoon; keep lamp doors closed except during cleaning or lighting.
- Report defective lamps to the Signal Inspector, and clean both inner and outer surfaces of lenses daily.
General Responsibilities
- Operating staff are tasked with cleaning and lighting signals and point indicator lamps.
- Station Masters must explain these maintenance instructions to staff and conduct regular inspections.
- Traffic Inspectors are responsible for periodic inspections of lamp rooms to ensure adherence to maintenance protocols.
- Each Signal Inspector must examine signals and lamps monthly, replacing defective items promptly.
- Report excessive lamp damage or neglect in cleaning to DSTE and DSO.
- All signal lamps must be overhauled annually, with overhaul dates marked on each lamp.
Color Light Distant Signal Operations
- Distinct aspects and indications for colour light Distant signals:
- "Caution" requires preparation to stop at the next signal.
- "Attention" indicates a need to proceed with caution.
- "Proceed" confirms the block section ahead is clear.
- Distant signals must be located adequately in rear of Stop signals they pre-warn; more than one Distant signal can be used if necessary.
- The outermost Distant signal must not display a less restrictive aspect than 'Stop' until clearance is obtained from the station or level crossing gates are secured.
Special Instructions for Distant Signals
- Under special instructions, a color light Distant signal may be combined with the last Stop signal.
- Such arrangements should ensure the Distant signal does not display a less restrictive aspect than 'Stop' until Line Clear is confirmed or level crossing gates are closed and locked.
