the right to the stop increases the
locomotive’s speed. Turning the
speed control knob to the left to the

locomotive’s reaction to each change
in speed, depending on how you have
set the acceleration/braking delay.
Turning the speed control knob to
the left past the “0” setting: Reverses
the locomotive’s direction of travel.
Important: On the 6021 Control-Unit
two arrows to the right of the
address display indicate the direction
of travel for the locomotive.

Arrow pointing down:
Locomotive runs in reverse.
Pressing the “function” button:
Turns the headlights on.
Pressing the “off” button:
Turns the headlights off.
Pressing button “f2”:
Turns the sound effects circuit on to
reproduce prototype sounds that
vary with the speed of the locomotive.
Press button “f2” again turns the
sound effects circuit off.
Pressing the “f3” button:
Pressing it once turns the sound of
the horn on. Pressing it a second
time turns the horn off.
Pressing button “f4”:
Changes the sound of the horn that
is activated by pressing button “f3”.
The two horn sounds differ primarily
