One reversing loop to support reversing in both directions off the mainline?
I am building a relatively simple O scale layout where I have a reversing loop within a circular mainline. It currently reverses trains in one direction using a PSX-AR in the reversing section. Ideally I would have a second reversing loop for the other direction but I do not have space. It occurred to me that I might be able to use the existing reversing loop by connecting from other mainline direction into the reversing loop entry point. Is there anything I am missing re: using a loop for both directions?
BTW I would post a sketch but I do not have the photo icon in the editor... maybe because I am new member moderated in this group.
Thanks for any thoughts here.
