RAILKING

NOTE: When locking the engine in the Forward or Reverse positions, the

whistle button will blow the horn. But when locking the engine into the

NEUTRAL position, the whistle button may turn on or off sounds of the bell,

coupler arming or coupler firing depending on the transformer throttle

voltage settings prior to the user’s attempt to lock out the engine.

Remember, the horn doesn’t’t blow in NEUTRAL (unless you programmed

it to do so using Feature 25. See page 20 for details), only the bell rings or

the coupler operates in NEUTRAL. While it doesn’t’t make any difference

on how the lockout function operates, you may hear one of the three

different NEUTRAL-activated sounds.

To unlock the engine from the NEUTRAL position, follow the process to

unlock the engine in the Forward or Reverse directions above.
