Study Notes
Automatic Block System on Double Line
- Trains on double lines, worked using the Automatic Block System, require continuous track circuiting or axle counters.
- Sections between block stations are divided into automatic block signaling sections, defined by consecutive stop signals.
- Track circuits/axle counters control stop signals ensuring the line is clear not only to the next stop signal but also for an adequate distance beyond it.
- Signals automatically change to "on" when a train passes.
- The adequate distance must be at least 120 meters unless specified differently.
- Loco Pilots must stop when encountering an automatic stop signal displayed at "on" with an "A" marker.
- They wait for 1 minute during the day or 2 minutes at night, then proceed cautiously if the signal remains "on", exchanging signals with the Guard and blowing the whistle as needed.
- The Guard must display a stop hand signal to the rear when the train is stopped at the automatic stop signal.
Loco Pilot and Guard Duties
- Loco Pilots must stop behind the "on" automatic stop signal (with "A" marker) and wait for a specified time.
- If the signal remains "on" after the waiting period, the Loco Pilot must contact the Station Master or Centralized Traffic Control Operator to obtain permission to proceed if the line is clear.
- If no telephone communication is available, exchange signals with the Guard and proceed carefully until the next stop signal.
- The Guard must show a stop hand signal towards the rear during stops at automatic stop signals.
Automatic Block System on Single Line
- Single-line systems require continuous track circuiting or axle counters.
- Traffic direction must be established from the previous block station before proceeding.
- Train movement must occur only after the line is declared clear to the next station.
- The line must be clear to an adequate distance beyond the next automatic stop signal, or the next stop signal, if a manual approach is present.
- All stop signals against the traffic direction must be on.
- Minimum equipment includes a home signal, a starter signal, and an automatic stop signal.
- Additional automatic stop signals may be added as needed.
- The Home signal should not be turned off until both the starter signal and an adequate distance behind it are clear.
