Welcome

DCC rail polarity is always reversing at a rate of knots so it matters not which way you connect them. It is more important if you are wiring in a socket and may be fitting a blanking plate for DC use pending fitting a decoder, this will ensure the loco runs the right way on DC.

If the loco runs in reverse to your normal dorection on DCC then you would just swap the motor wires.

If you think about your question logically. If you pick the loco up off the track, turn it though 180° and place it back on the track facing the other way. That is exactly the same as reversing the DCC track wires to the decoder. So no, it will not damage the decoder.

Hi joe, my apologies but my tongue is firmly in my cheek here - I think Chris’s reply here should be framed.  He’s answered a technical question using one only para, 4 sentences with 6 clauses.  Such restraint has not previously been seen in years of excellent replies. 

 

PS.  The answer to your question is no.

The answer might simply be No Fishy but often it is interesting to know why.
