Rail transport terms are a form of technical terminology applied to railways. Although many terms are uniform across different nations and companies, they are by no means universal, with differences often originating from parallel development of rail transport systems in different parts of the world, and in the national origins of the engineers and managers who built the inaugural rail ...
Signals are most commonly mounted on trackside masts about 12 to 15 feet (3.7 to 4.6 m) high to put them in the eyeline of the engineer. Signals can also be mounted on signal bridges or cantilever masts spanning multiple tracks. Signal bridges and masts typically provide at least 20 feet (6.1 m) of clearance over the top of the rail.

The advantage of the upper-quadrant signal is that should the signal wire break, or the signal arm be weighed down by snow (for instance), gravity will tend to cause the signal to drop to the safe "danger" position. In a lower-quadrant signal, the opposite may happen, sending the signal to "off" when in fact it should be illustrating "danger".
The earliest rail cars were hauled by horses or mules. A mounted flagman on a horse preceded some early trains. Hand and arm signals were used to direct the "train drivers". Foggy and poor-visibility conditions later gave rise to flags and lanterns.
FRC poles are hollow and similar to the tubular steel poles, with a typical wall thickness of 1 ⁄ 4 to 1 ⁄ 2 in (6 to 13 mm) with an outer polyurethane coating that is ~0.002 in (0.05 mm) thin. As with all the other non-wood poles, FRC poles cannot be mounted with the traditional climbing hardware of hooks and gaffs.
