Rh In order that the different descriptions of trains may be the more readily distinguished one from another, especially at night, a system of distinctive head lights for the engines has been devised, which is as follows:—

Where there are more than two lines (one Up and one Down) a Green Light must be carried at foot of chimney by Engines of all Trains travelling on the Auxiliary Line.

Light Engines on the Auxiliary Lines must carry one Green Light at the foot of the chimney, the Light on the Buffer Plank being dispensed with.

.—Urgent Express Goods, Cattle, Meat, or Vegetable Trains requiring unusual despatch, will, under special instructions from the District Superintendents, carry the following distinctive Head Signals:—

"By day—A White Oval Board, with Green Cross on it, at foot of chimney.

By night—One Green Light over Left Hand Buffer, and one White Light over Right Hand Buffer."

These special Head Signals must only be used in cases specified by instructions from the District Superintendents.
