Hello all,

I hope that someone out there can help me with an issue on my layout that has been creeping up lately.

I run a Digitrax DCC system (DCS 52 Zephyr) and there 11 locomotives on my layout, the majority of them (3 of 11) are also Digitrax decoders.

Recently, for example, when I've been running the throttle on my UP Trio (9660/322/660) another locomotive will also start moving (BNSF 3001 which I have consisted to BNSF 6340) which is not consisted with the other three.  If I un-consist BNSF 3001 with BNSF 6340 and run it alone, the UP trio does not respond.  I don't know what to call it except "phantom consisting".  I hope that makes sense.

Another example.  When I run UP 3024, at least one (but not all) locomotive in the UP will respond.  When I run the UP tio, UP 3024 will not respond.

I've tried resetting decoders, un-consisting and re-consisting, cleaning tracks and wheels, but the issue continues to creep up.  Last night, I had things working again, but then this morning, another crash.

Any thoughts or ideas?

Thanks!

Hello everyone,

First time poster, so I apologize if I'm placing this in the wrong spot and I'll try to post with as much information as I can.

I have three Bachmann HO scale GP40 locomotives on which I've attempted to install Digitrax DGTDH126D decoders.  I've been met with limited success.  Each locomotive was part of a train set (Union Pacific Pride of Prairie, CN Harvest Express, BNSF Rail Cheif).

The biggest issue I'm having is the Union Pacific GP40 makes a kind of grinding, jumpy noise similar to if the track or wheels are dirty.  I've cleaned the wheels and tracks in question.  It also doesn't respond 100% to the controls...i.e. won't stop when the knob is turned down.  I've also checked the connections between the decoder and locomotive and I don't believe I've made any errors.

My controls are the Bachmann DCC EZ Command and my track is Kato Unitrack.

Thank you in advance!

Tom
