OPERATING DWARF SIGNAL
The Dwarf Signal is modeled from a type of two-light signal which finds many
uses in real railroading. The main advantage of dwarf signals is their small size
and economy. They do not require expensive overhead structures and can be
conveniently located between close parallel lines of track. Dwarf signals are
generally used in slow-down areas, such as yards, sidings and terminals and
also as “back-up” signals for trains going the “wrong way” on main lines.
Dwarf signals usually have a green and red indicator light, but sometimes, when
used for “call-on” duty their green light is replaced by a yellow light. A call-on
signal is a supplementary signal which permits a train to proceed with caution
even though the main signal indicates the track ahead is occupied. Call-on
signals are used to control the movements of a second section of train and also
near terminals or stations where there is heavy train traffic. A No.153C contactor
is supplied with the dwarf signal.
INSTALLING THE 153C CONTACTOR
TRACK TIE
PRESSURE PLATE
Slide the contactor beneath the track so that one of the track ties rests
firmly upon the top pressure plate (See Figure 1). If your layout is
fastened to a board or platform, loosen several sections on either side
of the contactors. The track must be able to bend under the weight of
the train. For the same reason, the contactor may not work properly
when placed next to a track switch.

Have an adult strip one quarter inch of insulation from both ends of all
four wires included with your accessory if they have not already been
stripped. Connect one end of each of the wires to a terminal on the
Dwarf Signal, then connect the other ends to the contactor and
transformer, as shown in the illustration. To connect the wire to the
contactor terminal clips, press down the springy upper half of the metal
loop until the lower half projects through the slot, insert the bare wire
end into the loop, and release the upper part of the clip. Spring tension
will hold the wire tight.

ER HOOK-UP TO TYPE 4690

ADJUSTING THE CONTACTOR
After all connections are made and the transformer is on, the contactor
must be adjusted so that the Dwarf Signal operates properly. Stop the
train several sections away from the contactor so that it does not press
on the contactor plate. Turn the adjustment nut just enough to cause
the red light to go out and the green light to go on instead. When properly
adjusted, the contactor will respond to a light finger pressure on the
track and the red light will stay on as long as any part of the train is
passing over the contactor plate. If the action of the two lights is
reversed, interchange connections marked #1 and #2 on the contactor.

ALTERNATE WIRING
If desired, the dwarf signal can be hooked directly to an 0/072 switch.
When the switch is thrown, the signal will automatically change colors.
If you want the opposite light sequence, reverse the two outer leads at
the switch (this hook-up will not work on 027/042 switches).
