Tips on Using PSA
• You can terminate PSA at anytime by turning off power to the track for 15
seconds.
• You do not have to be in Forward to use PSA. At the conclusion of the full
sequence, the train will pull away from the station in whatever direction you
were going when you activated the feature.
• You can use PSA even if you are double-heading with another engine. If the
second engine is not equipped with PSA at all, you must remember not to leave
the throttle at a high voltage level once you have stopped the engine to run the
PSA. Otherwise, the engine without PSA will begin vibrating on the track as its
motors strain to move the train, since they cannot be automatically disabled
during the PSA cycle. If the second engine is an original Proto-Sound engine
equipped with PSA, you may choose to disable it when used in double-heading
operations, so you will not experience competing PSA sounds. To disable PSA
in an original Proto-Sound engine, see the operating instructions for that engine.
• PSA can be triggered from Neutral. It will operate the same as if triggered
while in motion except that, at the conclusion of the PSA, the engine will depart
in the next direction of travel, as opposed to the direction it was traveling before
entering Neutral.

3. After waiting about 30 seconds for that sequence to run, press the Direction
button again to trigger the second sequence of PSA.
4. After about 30 seconds, press the Direction button again to trigger the third
PSA sequence.
5. Again, after allowing about 30 seconds for that sequence to run, press the
Direction button one more time to trigger the fourth and final PSA sequence.
You will know it is the final sequence when you hear the “All Aboard!” call.
The bell will begin to chime and within a few seconds, the engine will start and
move out on its own at the current throttle setting, in the same direction it was
traveling when you began the sequence. Once the bell turns off, the operator
regains control of the transformer’s bell and whistle buttons and can ring the bell
or blow the whistle as usual.
