Thank you Phil for this information most useful I'm not sure what NMRA stands for but I presume this is what is on my gauge 1 engines,
I' still not clear why when they go through the blanked off sections of track when set to live, they run backwards, these blanked sections are
controled through the central station l.g.b. boxes.
NMRA = National Model Railroad Association
A body that oversees the DCC 'standards', amongst other things.. They came up with some conventions that mean our trains should behave in the same way on each other tracks..
The reason certain of your track sections behave differently:
Under DCC there is power on the track, but it is not this which controls the direction a loco will run.. That is done by the commands you send to the decoder in that particular loco.
This means you can swap the wires to the track, and the loco will still travels in a forwards direction when your Central Station tells that decoder 'make the loco go forwards'.
This is not true for your analogue loco's, which rely on track-polarity to set the direction they will travel..
If there are only certain sections of your track where this is a problem, then swap the wires feeding those sections of track over, and that should solve your problem.
Don't worry about the comments.. We tend to have a laugh at each others expense on here. No harm was meant, just a bit of 'banter' between other members of the Forum.
