Rule 17: for dimming lights on locomotives
Rule 17 is actually a collection of rules that govern which lights are to be on on a locomotive at given times and to when they should be dimmed. These rules may vary from railroad to railroad but generally follow a similar pattern. The general purpose of the rule is to make sure that the locomotive is visible, without creating undue glare for others in the area.
- Except when an engine is clear of the main and stopped, both the front (and rear if so equipped) headlights should be on.
- The light in the direction of travel should be a full brightness except:
- 1. At stations and yards where switching is being done.
- 2. When the engine is stopped close behind another train.
- 3. In non-signaled territory, when the engine is stopped on the main track waiting for an approaching train.
- 4. When approaching and passing the head end and rear end of a train on the adjacent track.
- 5. At other times to permit passing of hand signals or when the safety of employees requires.
- The opposite light should be dimmed.
Rule 251: giving trains authority to move on signal indication in one direction
When track is signaled in only one direction, signal indication will be the authority for trains to operate with the current of traffic. Movements made against the current of traffic will be governed by non-signaled DCS rules (see Rule 261: reverse movement beyond the limits of the block).
Rule 261: giving trains authority to move on signal indication in both directions
Signal indication will be the authority for a train to operate in either direction on the same track.
Rule 261: reverse movement beyond the limits of the block
Where Rule 261 is in effect, a train must not make a reverse movement
beyond the limits of the block without verbal permission of the Dispatcher (or
Operator when authorized by the Dispatcher). Before permission is granted, the
Dispatcher must determine that:
1. The track to be used is clear of opposing movements,
2. Signals governing opposing movements are in Stop position,
3. Blocking devices are applied to protect against opposing movements.
Verbal permission to re-enter must be given in the following manner:
“No. 5306 engine 4129 reverse direction on No. 2 track at MP 5 and proceed west to MP 6.”
Movement must operate at Restricted Speed until governed by a more favorable signal.
Rule 504: for trains doing work within Traffic Control System
When a train or engine is to do work, or occupy track
or tracks within specified limits, where Rule 261 [giving trains authority to
move on signal indication] is in effect, permission must be obtained from
control station, specifying time and limits, and tracks to be used. When the
train or engine has entered these limits control station must lock all signals
governing movements into such limits at “stop,” and locks must not be removed
until the train or engine has cleared the specified tracks within the limits.
Tracks specified may be used in either direction within the specified limits
without flag protection.
Train or engine must be clear of tracks specified within the limits by the time stated and will report to control station when clear. When additional time is required, it must be authorized by control station before expiration of previous time limit.
Where the control station is not operated by train dispatcher, such permission, working limits, and specified tracks, must first be obtained by the control station from the train dispatcher.
