>I was wondering if a reverse loop module would work with Hornby Digital and if you had a non isolating point would there be any issues?

A reverse loop module is required regardless of the behaviour of the point. The problem with a reverse loop is that the "left" rail eventually makes contact with the "right" rail which means you have a short. The reverse module deals with this problem by detecting the short and switching the polarity in the loop so that at the point of contact the polarities of the rails are correct.

This is another area where Allan Gartner's website has clear diagrams which explain what is going on. You can get to it via this forum's Links - DCC section.

A couple of points (no pun intended) here:-

1) To post photos / images / diagrams etc, this topic explains how.

2) The reverse loop module applies the polarity change to the track in the reversing loop, not the rest of the layout so sanity is maintained for all concerned.

I don't think we've had a topic on triangular junctions, so if you could get your image loaded, it would be great to have the accumulated wisdom of the Forum applied to it. The thought that occurs to me is that the distance through the triangle is a lot shorter than a reverse loop. If you don't restrict the triangle to one loco in steam as it were, you might need a reverse module for each leg??
