4.2.1 High Controlled Signal
 The high
controlled signals control and guide the trains into the yard. These
signals will normally have two units of three aspects in line. The
upper unit corresponds to the main line and the lower unit corresponds to the immediate
loop line. Some high controlled signals will also have, below the second
unit, a third unit of one aspect (AMBER). These are found at the points
where there are more than one turn out. The second unit have a speed
restriction of 48 km/h and the third unit has 16 km/h. The meanings of the
aspects are given below.
