Funnily enough, i noticed on some second-hand points i have, there is a switch that gives a byest to the left or right on the points spring. i wonder if this maybe enough. ThanksThis should help: Automatic model railroad reversing loops for DC, DCC or AC
Top loop shows this, ignore any words. The loco enters from the left with the points set for straight on, runs round the loop and exits back onto the line to travel back by pushing through the points. These will then spring back to be set for the next train coming from the left.
The lower diagram shows you an automatic continuous run.
I use LGB points and they have good, positive push through action.Funnily enough, i noticed on some second-hand points i have, there is a switch that gives a byest to the left or right on the points spring. i wonder if this maybe enough. Thanks
