Plan with Reverse Loops?
Posted by wickman on Saturday, December 19, 2020 11:30 AM

Hi folks I just finished laying track and want to add the following , two DCC Specialties On-Guard OGAR autoreversers , two DCC Speciaties Hares for auto throw, DCC Speciaties PS4 Circuit breakers for 3 power districts. I'm using a Digitrax SuperChief dcs200 with 8 Amp powersupply, DS64's to control Tortoise slow motion turnout switches.

 I'm in the process of cutting the gaps for the DCC Specialties OnGuard auto reverser on the new room section , Room#2 ,I marked on the attached Plan in thin red where I was going to make inside and outside rail cuts for the reverse sections for each room. I'm concerned about the rail I added for the station that runs parellel to the mainline of the reverse track in Room #1 ( "green added track for station"). 

I'm not certain if I added another potential for a reverse track needing its own auto reverser? If so I only have two OGARS and would I be better off removing the cross over track labeled in blue as "  problem" ?

Thanks again

 I won't get into potential problems with the Hares yet.

I'll take a better look and reply better than what I just posted [Edited]

I think you should have a gap at the left end of the turnout to the left of the blue problem arrow, and then at the top where the turnout affords acces to the new track.  That's all you need, one circuit monitor/reverser for all of that folded loop-back.  The station tracks on either side are all flowing the same way, if you wire them outside/inside rails, and there's no conflict there.

I think Selector is saying the same thing - the track you have marked as 'problem' is the reverse section - between there and the turnout at the top left of the station. Selector's suggestion shgould work. There may end up being more than oen train in the isolated track when one enters or exists the reversing section, but that won't hurt anything, the reverser can handle it.

 My concern is with the other isolated section on the lower right loop - is that at least as long as your longest train? If not, you can do the same thing with that loop - just put gaps right at the diverging legs of the turnout to the left of where the one gap is already marked, and make all the track in the loop, including those sidings, part of the reversing section.

I agree with Selector, there is no reversing loop next to the station.

I see a second reversing loop starting at the turnout above the upper most left mark going left and counter clockwise.

How are you managing the reversing that will happen at the turntable?

Ok just playing around in room 1 , its a mess because I had removed rails to add on the second room, I actually noticed two plastic joiners to the left as Selector had suggested and I was trying to get an engine to short out the but it didn't happen, I had to run a couple wires to the new rail and the engine puttered a bit but no kicking out. Quarter test worked everywhere ok.  I followed Selectors lead on "and then at the top where the turnout affords acces to the new track" , there is no plastic gaps where was suggested, weird.I must have wired things up as was suggested back in 2014. I have to connect the rails up to the trestle and see if I can run the CMX cleaner around and get room 1 sorted out before wiring up room 2, I need to find out how this is running without shorting.

 

Sorry Randy I'm not understanding what/where you are suggesting?

 

Henry I haven't even thought about the TT yet, it's a Walthers 90', back when I had it installed , probably 2006, I didn't use any reversers for it, is it possible it is built in?

Thanks

 I'm talking about the reversing section in room #2. Is it long enough for your longest train? If not, you can expand it to include the entire loop by putting the gaps on both diverging legs of the turnout to the left of the upper gap you have marked. Both sets of gaps there, at that turnout, and everthing within the loop runs off the autoreverse.

 Is the turntable the built up one, or the kit one? The built up one with indexing does not need a reverser, it's built in (which is why there are spots marked where you aren't supposed to run any tracks - those are the dead sections for the contacts to swap at the bridge rotates).

Thanks Randy yes I do think that stretch is long enough for the longest train, I didn't want to go any higher with the top gap as I still need to cut in at least one gap for the Hare control autothrow for the switch at the beginning of the loop coming from room 1. I had actually thought about moving the lower gap around the bottom of the loop to the points end of that switch. In the past I've been able to add gaps in the corners ( loops ) but it always took a bit more messing around. 

I'm thinking with the Hare that I can get it to throw 2 sets of points at once, I believe it is possible. 

Yes it is the Walthers built up TT so its probably good to go.

Thanks Rich , I had missed your post, I'd like to know how you posted  pic :)

 

On another question I am using Dcc Specialties Hares as well and realize I need one trigger gap ( only one because of insulfrog ) , can I use the same gap wire that is used for the OGAR for the Hare trigger wire? Seems I should be able to.
