Rule 20. Classification Signals

The following rules for the use of Marker and Rear End Lights are taken from the rule book titled Consolidated Code of Operating Rules - Revised 1959 to take effect December 1, 1959.

Note: On engines provided with places for display of signals on either end, the classification signals must be displayed on the leading end of the engine in the direction of movement.
Rule 20.
All sections except the last must display two green lights by day and by night on the front of the engine.
Rule S-20.
If both green lights fail enroute, train must stop and notify inferior trains that are met or passed and also trains at train order meeting points.
Rule 21.

Extra trains must display two white lights by day and by night on the front of the engine.
Rule 22.
When two or more engines are coupled together, each engine must display the required classification signals.  The leading engine only will give and answer signals.

Exception: In CTC or Rule 251 territory, a helper engine moving over only a portion of a subdivision need not display signals.
Rule 23.
One light displayed, where in Rules 20 and 21 two are prescribed, will indicate the same as two; but proper display of all train signals is required.
