between suppliers and railways, but they must be high enough
so approaching trains can easily see them. See Rule 846, CROR
in the sidebar. Cloth flags with a metal stake on each side of
the flag are used along the side of the track to indicate slow
orders, stop orders and resume normal speed.
Some blue metal signs have lettering on them to tell staff what
type of work is being done on the equipment. As an example
a blue sign might say, “STOP CREW AT WORK.” Metal signs are
usually blue, but might also be red, yellow, or green and must
be painted on both sides. For those modeling the modern era,
these signs must be reflective. In some cases a white reflective
border is used on blue signs. The era being modeled will deter-
mine whether or not trackside flags are metal or cloth. For
maintenance crew convenience almost all modern trackside
signs are cloth.
