    You're using an O6 Cab. Train stalls and won't go via giving it a push. Something is shorting system or such. You shut off main power and go look over the RR to find the culprit. You find it, correct it and turn power back on...Engine you were running now 'floors it' and speeds down the track !!! Yeah, I know, I didn't turn the O6 throttle to zero first...This IS one facet of this type of train control I hate... It's because there is no speed step displayed on O6 nor a simple calibrated panel surrounding the wheel (as is an old MRC Tech II). It can't as 06 wheel makes many 360deg. spins to Accel or Decel..
    I wish it were designed to go back to 0 speed when it sees power-off. It's a bummer visually as well as dangerously as loco now inevitably speeds toward a wrong thrown switch or another parked engine....

    Hi Mark -

    The place to post this question is the NCE-DCC group on Yahoo. If there is a solution to your problem, someone there will provide it. You may get an answer here as well, but the Yahoo group is the best source for NCE info.

    There is no reason NOT to post your question here, Mark. Hopefully someone here will have an answer for you. I am merely suggesting that the best place for answers will be the NCE-DCC group. I am constantly amazed at the degree of expertise in that group!

    TrainBoard is still my favorite forum!

    Bump... I have had a very similar problem from time to time, maybe once a month. Until I read this post, I had never attributed the problem to the cab06. I will be more wary next time it occurs to identify the problem. Thanks for the post.

    I don't have time at the moment (yay leaving for work in ten) but I recall reading about this problem somewhere else - Perhaps a google search will turn up the results you wish for. Have you tried deleting and rebuilding the consist?

    First of all, the driver is suppose to have full control of his loco at all times..

    Second, disable the DC option on the decoder. Many have reported in different DCC forums that a glitch like you mention can cause a loco to take off at full speed.

    Rich, that's a new one on me...I'll check it. I assume you mean analog mode or some other analog CV needs changing/turning off. But, I am 97% in control of train at all times. What I am referring to is more a visual problem with the O6 in not knowing where we last left its speed step, say. I do now try to remember ("Try to Remember the kind of September when Life was...... OOps I wandered off there.....) to roll O6 wheel counter clockwise a few spins to make sure it is at zero. But I don't always remember to. I guess I need to tweak my engineer's skills........Mark

    The best piece of train control hardware I have is a ~$13 Remote AC power control (A little box with one button that hangs around my neck). It never fails to stop the trains, even when I don’t have the train control unit. (Also, I do not have to worry about DC runaways.)

    Bob, I'm not getting it. We are running DCC I assume. What is this AC (?) thing around your neck. I realize I could merely short out system with a metal object and, with no power districts everything will stop dead. What is it you do with this gadget ? I'm lost ?

    I think it controls the AC power going into the NCE system, when you hit the button, it's like pulling the plug on the DCC (no AC in, then DCC no go).

    Maybe like a remote light switch device.

    Dogtags. Lay across the track, and POW! shutdown.
    Heck, 60 years ago we were doing that with half dollars on Lionel 3-rail.
    Except we'd do it to trip the e-unit to neutral remotely, then trip to reverse.

    Digitrax is the same way. Unless you return the throttle to 0 your train will take off when the track power restores, although it does have a speed showing on the DT 400 series throttles. The UT series throttles have no speed indication so the same thing happens. You just have to get used to it.

    Mark,
    I should have call it a “Remote AC Power Switch” You can see the one like I have here: http://www.ebay.com/itm/1-in-Pack-W...t=Home_Automation_Modules&hash=item1c36901a41

    10-4 ! Got it. it's a transponder to shut main power...Nice ! Mark

    Typically, all DCC decoders come set up from the factory to operate under analog DC. You can disable this feature by setting the appropriate CV value, or by using a program like Decoder Pro to change it. If you do not disable analog DC operation, the decoder will interpret the return of power after the short as DC power and the loco will take off in Run 8! And that's not any fun at all, I can assure you. I use Digitrax, but I am fairly sure NCE behaves the same way. Hope this helps.
