As I think I've mentioned the layout will be DCC operated. I like driving locos, not the track, nor do I want to be tied down in one spot to flick switches all the time.

With DCC control you can automate reverse loops very easily, but just how easy I didn't realise at first!

the initial plan was to use a reverse loop module. This switches the polarity automatically when a train drives into reverse loop. The units do work well, but are not free. In addition to this I had questions if they might interfere with track power cutout module (A MERG kit). If that gets even a hint of a short circuit it will cut the power to tracks (The DCC bus to the point decoders is a separate bus, which is taken from the booster before the DCO).

I'm also applying power to the frog, so that needs switching as well. In the end the solution is pretty simple: Flick the power to the loop (and frog) at the same time as the point.

Even more so, the return loop is one way, so I can even automate it.

A train detector is placed a bit further away than the length of the longest train (loco + 6 or 1.2m/4ft, for HOe), when this is triggered the points are automatically set to allow entry to the loop.

A short piece of track at the exit of the reverse loop, throws the points to allow exit. As the train embarks on the climb back to the scenic area, it will trigger the entry detector, this will reset the points again (hence why it needs to be more train length away from the reverse loop.

A rough sketch here:

The selection of a fiddle yard track will flick both the entry and exit points for that track. It is envisaged to use a series of diodes to set the points in the ladder leading up to it as well. So you would simply need to select the track you wanted to use.

The two stub tracks at the bottom of the picture are for storing rail cars, push pull sets and the draisine (or any other kind of odd ball vehicle). The left hand end might also become the programming track. I'm not sure, if it will be there in the end as access is not as easy as somewhere in the open. The current layout has a stub track in the station as the programming track and is switchable.

The HOm fiddle yard will have something similar, however at the end of the each of the loops will be an ABC braking module. This means the loco can be made to stop in the correct place of its own accord. All my HOm loco's (except for the station shunters) are being fitted with ABC capable chips. One of the stub tracks, will have the ABC near the point, the other at the far end...

As most of my HOe loco's don't have this, there is no point in installing ABC modules....
