Do you know what decoder is in your locomotive?  Are you operating in DC or DCC?

What did you get when you tried reset? (CV 8 set to 8)

If it's new Broadway Limited locomotive then it's probably a Paragon3 decoder, which has had it's issues.  I would try resetting the decoder back to factory standard by changing CV8 to "8" then cycling power - i.e. turn your DCC system off then on.  That will return the decoder address back to "3".  You can then re-address your decoder to whatever address you were operating it on before.

Before doing that: Have you tried operating your locomotive on address "3" to see if it will run?  Worth trying before resettting.

Hi Tom                                                                                                                  That's the problem, it happened while it was in factory setting "3", it's has a sound decoder,  I have lights, but no sound or movement.

Okay, just so I'm clear: Did you perform a factor reset mentioned earlier using CV8=8?  Whether you did or didn't, try it again and cyle power immediately afterward, as that might clear up any anomolies that may be happening with the P3 decoder.

As mentioned, those particular BLI decoders have been notoriously problematic.  If the reset doesn't clear up the problem I would try contacting the BLI Service Department by email.  You may need to ship the locomotive back to BLI for inspection/repair.  Shouldn't cost you anything if the locomotive is new.

Function 8 is usually the engine start function. I have had locomotives sit there, silent, with lights on waiting to go but unresponsive to throttle. Pressing function 8 sometimes starts them up again.

But F8 wouldn't affect movement; only sound.  Something else must be going on if the locomotive is not moving.

To the OP: Does pressing F0 turn your headlights on and off?

Terrific!  Glad to hear that worked for you. Yes

Like with a Windows PC - sometimes a simple "reboot" (decoder reset) is all you need to fix a sudden quirky or unresponsive decoder.
