RailKing 4-Car Subway Set Operating Manual
RAILKING
TAS will automatically reengage the motor and the set will proceed away
from the Subway stop. Like Option 1, the set will continue on in the same
direction it was traveling
before TAS was activated.
Option 3 - Automatic
Layout Configuration
The TAS feature in the
Subway Set can be
automatically triggered on
a layout by configuring
insulated pieces of track
near the designated
Subway stops around the layout. The insulated track sections (center rail
only) need to be attached to the transformer with a diode in the line to create
a negative DC signal (the same signal created by the bell button) and be
long enough that the signal will be outputted for at least 3 seconds (the time
it takes to activate TAS by pressing the bell button). In short, the insulated
track section and diode are acting like a bell button. Whenever the car runs
through the insulated section, it will receive the negative DC signal and
TAS will be activated. Because the diode reduces the power to the track,
the car will also slow as it enters the insulated track section. The key to
making this option effective is using a section long enough to create the 3
second “push” of negative DC without slowing the powered car to a
complete halt. It is recommended that the operator attempt to have the rear
roller of the powered car
leave the insulated track
section shortly after the 3
second push of negative
DC has been received by
the ProtoSound® module
inside the Subway Set
powered car. This way,
when TAS has completed
its sequence, the powered
car will be sitting on a
track section with enough
power to sufficiently get
the set moving again. Adjusting the overall track voltage will help adjust
the speed necessary to carry the car through the insulated track section but
