It will not change the direction of the loco anyway, because that is controlled by the decoder !

I would disagree with mty. The automatic switches for reversing loops switch polarity whilst the loco is moving, as the loco and decoder are not affected by the polarity of the supply. Just don’t send commands whilst switching the polarity.

I can’t see any reason or need.

However, it’s your railroad. when switching I upling.throttle down then reverse direction without stopping when unco
