status edit the decoder so that it will run.

4.6 Locomotive “buzzes”

Most noisy locomotive issues are caused by vibrations inside the loco’s mecha-

nism. For DCC equipped locos, try lubricating the locomotive’s brushes and

tuning up the loco’s mechanism.

Analog locos (without DCC decoders) make a “singing” sound when sitting

still on DCC layouts. This noise, which is caused by the DCC track signal,

decreases as the analog loco is accelerated. You can significantly reduce this

noise by using conductive brush lubricants and by assuring that there is no

vibration inside the loco that will add to the noise generated.

When operating analog locos on DCC layouts, DO NOT leave analog locos sit-

ting still. It is best to park them off the live track unless they are running. This

will prevent heat build up that can damage the loco, minimize the humming

noise and lessen stress on the motors.

4.7 The Quarter Trick

If your track does not have adequate power supply to the locomotives, then

the DCC signal won’t get through either. Use a coin or screwdriver blade and

go around your layout creating electrical shorts every 10 feet. Your boosters

should indicate a short by beeping (or in the display for Zephyr units) and shut

down track power when the short is present. When the short is removed, the

booster will return to normal operation. If this does not happen, then you need

to add more feeders to make sure the track has enough power supply to oper-

ate.

4.8 Are your LocoNet Cables built correctly?

Check your LocoNet cables with the LT1 tester to be sure the cables are good.

If your LocoNet cables are not working correctly, the signal won’t get through.
