Is it ok to have a reversing loop with sidings? 15 feet worth?
Not really visualizing what you are asking.
If the question is, "Can I take spurs off a reverse loop?" the answer is, "Yes, but you have to cut gaps and arrange feeders if you use hot frog turnouts."
If the question is, "Can I have a passing siding entirely within the electrical boundaries of a reverse loop?" the answer is still, "Yes, but you will have to put gaps between the frogs if you use hot frog turnouts."
If the question is, "Can I have concentric reverse loops, with the reverse loop gaps after the frogs of the turnouts?" the answer is, "Yes, but then each track is a separate reversing section."
Note my emphasis on hot frog turnouts. All of mine are hot frog types (Electrofrog in Peco-ese) so I have to be conscious of the possibility of unwanted shorts and inadvertent opens.

As Chuck indicates, it depends on the track configuration on your particular layout. A diagram would be helpful.
In general, there is no reason that a siding cannot be incorporated within a reverse loop. The only concern os that no portion of the siding can run outside the reverse loop unless the rails are properly gapped.
How about a track diagram?

Your terminology is a little unclear.
If you are asking for our permission or our blessing, you have it. Proceed with your layout design!
If you're asking whether such things are possible within the laws of physics as they apply to electricity, yes, they will work, provided you wire the track correctly. To be able to give you advice on that aspect, we really need to see a picture of what you're planning to do. Can you post a picture or simple diagram?

Hello scookam, are you out there?
I built mine with turnouts from Atlas. No special wiring for the one that feeds a dead ended spur, Standard block gapping on the turnout that feeds traffic to and from a loop that connects with an interchange track. Both work just fine as long as my dinosaur brain remembers to push the right buttons in a timely fashion, since The Cascade Valley RR still operates on a DC panel to complement the code 100 rails.

I am thinking of doing a double wye with a reverse loop off of one side. I think i will have to isolate all turnouts and wirer each with feeders. this IS prototypical. The NYO&W did this in Sylvan Beach aka Fish Creek. i will send a diagram asap.
Well, we seem to have lost the OP, but we have a new challenge on the wye! Get some diagrams up, folks!

So, where is the diagram Owendubya?
I will get one up over the weekend. I hope... haven't put up a diagram on here before.
Howdy again. Sorry about not answering back but have been trying to get my teen to show me how to put a diagram on this pc. He's sleeping of coarse. However, I believe you all have answered my question even though it was quite vague. I do thank you for the info. Scookam
Scookam, glad to hear that, but wake up that teen and post a diagram for us to see.

Teenagers should never be allowed to sleep, especially in the summer. Wake him up and put him to work!
i promissed id put this up and here it is. the yellow area is the reversing loop, the blue "I" sre where i THINK the insulaters should go. before the turnouts and between the wyes. the green "I"s are where i think, on the turnouts the insuators could be put, im not sure. any advice folks?
btw this is my centenial post.
my apologies, the link didnt work, i will fix it and re*6st

Owendubya, you are killing us! LOL
lol here rich
Owendubya, congrats on your 100th post.
I have prepared a two rail track diagram using blue to show one polarity and red to show the other polarity. The reverse polarities are shown where red meets blue and blue meets red. Those rail joints need to be insulated, as indicated by the solid black circles. The clear circles indicate where insulated rail joiners should also be placed to avoid shorts occuring outside of the reversing section once polarities are flipped (either by auto-reverse units or toggle switches).
Of critical importance here is that trains be shorter than the distance between the insulated rail joiners. Otherwise, problems with reverse polarities can still occur.
rich, i really appreciate it. as i understand it where the turnouts meet the wye have to be insulated. i can see why the turnout to the left if the double wye wouldnt need insulation. if i were to put in a turnout between the wyes heading to the right the right turn would need insulation but not the straight. eventhough the right turn is a deadend sand pit.
it may look odd but it was something that the NYO&W had in Sylvan Beach, NY. i got the info from John Taibi's book "when the railroad went to the beach". here is an 1898 map.

owendubya, that is correct. The divergent leg would require insulated rail joiners in order to keep the entire turnout inside the reversing section.
I prepared a revised track diagram to show this. I also added a series of solid black hash marks to indicate the uninsulated rail joiners outside of the reversing section. The rail joiners on the straight ends of the wyes within the reversing section are indicated by white hash marks outlined in black.
8am no coffee and it makes sense. im in trouble. lol guys, call me owen or gary (my real name) i really appreciate the help. when this project gets rolling i will definatly have pics for the site.

Good luck and be sure to post pics.
