Rule 24. Trains may be identified by indicators displayed on the engine when so equipped, which must have the train number or engine number properly displayed. The train number must not be displayed until the engine has been coupled onto the train. When the number of a train is changed, the indicators must be changed to correspond. Before making such change, the movement of other trains must be safeguarded.
When two or more engines coupled are handling the train the leading engine only will display the indicators, except when the leading engine is a helper or other engine for movement only over a portion of a subdivision. If the leading engine is not equipped with indicators, the next engine so equipped will display the indicators.
When an engine is cut out of a train, the train number must be removed from the indicators promptly.
Indicators will be displayed in the manner illustrated: (See above)
