Includes Signal Connections

The Yard BitSwitch is used to prevent equipment entering the main line from exiting a yard siding when the exit turnout is closed.  When the turnout is closed any train exiting the yard will observe a red signal and brake to a stop until the exit turnout is thrown at which time the signal will display green and the train will be allowed to enter the “ Main Line ”.  The Yard BitSwitch can be used with twin coil or Bi-polar turnout motors.

The Yard BitSwitch can be used to create an automatic ladder for as many yard sidings as might be desired.  IF THE LADDER IS BUILT FOR 4 SIDINGS THEN A MINIMUM OF 4 TRAINS IS NEEDED FOR OPERATION OF THE LADDER. One Yard BitSwitch BitSwitch is needed for each siding and the installation of accessory decoders (Digitrax DS64, NCE Switch-It, Switch-Kat, Snap-It or similar) capable of connection to additional track triggers (reed switches) arranged in a fashion similar to the following to automatically throw the turnouts as indicated.

*NOTE the GREEN triggers are not required if the main line will never have more trains than the number of sidings.  If there are more trains than sidings then additional BitSwitch controls need to be incorporated to prevent trains entering the yard before there is a vacant siding!

The Turnout trigger located in:

Yard line #1 trigger 1C,3T,4T closes turnout #1 directing the next train to alternate sidings, & throws turnout  #3 directing the next train to yard line #2 & throws turnout #4 releasing any train that may be parked on yard line #2.

Yard line #2 trigger 3C,5T,6T closes turnout #3 directing the next train to alternate sidings & throws turnout  #5 directing the next train to yard line #3 &  throws turnout #6 releasing any train that may be parked on yard line #3.

Yard line #3 trigger 5C,8T closes turnout #5 directing the next train to last siding #4, & throws turnout #8 releasing any train that may be parked on yard line #4.

Yard line #4 trigger 1T,2T throws turnout #1 directing the next train to yard line #1, & throws turnout #2 releasing any train that may be parked on yard line #1.
