Reverse loops

Post by Surovi »

Reverse loops or not?
I would like to have reverse loops but ...are they good/safe for locomtives?
Thanks!

Personally, I avoid reverse loops wherever I can, but I would not completely rule them out.
So much as wiring is done properly with proper controls, reverse loops can indeed be safe for locomotives.

On our TTTracks layout there are three reverse loops and they work well. I believe they are operated by Frog Juicer controller - but I didn't do the wiring. This is DCC only. Frog Juicer has a web page which shows wiring. Locomotives are safe. Any faults just shut off the DCC power at the command station. The limitation is that the train can't be longer than the loop.

To clarify, of course a train can't be longer than the loop or it would hit itself. However, the TT Tracks layout has the loop returning to a parallel track, not the original track, as shown in one photo, so the trains can be longer than the loop physically but not electrically. Train length is still a factor. The layout was a double oval, basically, and the parallel tracks have the same polarities. Recently the ovals were opened to allow access inside the layout and this was done with the loops. The polarities of the loops have to be managed. In the photo one of the electronic units can be seen beside the hinge.

The other photo shows the standard kind of return loop. This was made by Bjoern (CN-TT) who used earlier smaller radii modules. The electronics not only control polarity but operate the turnout automatically for the outgoing train. The short distances and the time to actuate the turnout mean the trains can't be going too fast. But it's cool to watch it work.

Thanks!
I want reverse loop to original track.
I don`t like parallel tracks :mrgreen:

Hi!
Do I need active point for reverse loop or it can be done with something else?

It does not really matters. Both switches will work.
