Yes, you can use single wire over yard and siding trackage, and be prototypical.

As to the question about having both a pole and a pan on a small roof-- I remember seeing a photo of a steeple cab with a pan, that in the down position,  took up the whole roof. The pole was mounted BESIDE the pan, and the pole had a Z bend to get the wheel over to the centerline of the loco.

Pole position is somewhat critical relative to the car body--or rather to the wheels under the body--and I cant imagine that setup being trouble free as far as staying on the wire. Being a steeple cab however, it might have been an arrangement to get access to just a siding or two, and when in use, a crew member would have his hand on the rope coming down from the end of the pole--to guide it. This happened often when switching moves were done with a pole--a solution that isn't available to we modelers.

Please don't ask what line the steeple cab that I'm referring to ran on--- it's probably been 50 years since I saw the photo-- however, if both my functioning brain cells stop fighting and declare a truce I MIGHT remember where I saw the photo, and will amend this with the info.

I have gotten the reverse loop in place on the club pike (HO, 8" radius").  At the moment, not being able to get the necessary single arm bracket poles, we are running two-rail DC.  Ahead of this year's holiday season open houses, I'm looking for thoughts/info on an automatic circuit that will reverse the polarity and throw the loop switch machine.  We want the line to be able to run with little or no supervision. 

If we can get the needed overhead materials to string wire, we intend to go to DCC.  The overhead will obviate the need for the auto reverse, but we will still need the turnout thrown automatically.  Any thoughts/direction/possible electronics suppliers welcome.

I'm unable to help you with your two rail problem, since the last 60 years I have run with live overhead, and both rails grounded, and 5 or so years ago, built a couple of additional locos that have radio control and on board batteries

If you have a live overhead--and if you are going to hang overhead, why wouldn't want to make it live-- the problem disappears. All you need is a light spring to hold the points in one position, and a car coming up to the switch after rounding the loop will push the points over. If you know what you're doing, and hand lay the switch, you can have this happen without any springs or moving parts in the switch--I have done this many times. No electronics needed.

Herb: Thanks for the response. As I noted, the ultimate goal is working overhead, but Alpine hasn't been very responsive thus far to our request to make the single arm bracket poles. Just by way of background, the club's trolley line will have an around the city block loop in street trackage, then the line that's now in goes on PROW for about 20 feet to the new reverse loop. Ultimately, another line will go out the opposite direction from the city area to the carbarn, with a long interurban line extending from there about 60 feet to the far end of the layout.

Hadn't gotten as far as looking for this topic yet - have supplies to build some G scale overhead for a 8ft display shelf for HLW Sparky in freelance RR livery.
Just have to get off my rear end and do it.

After reading whole thread now, haven't seen this reference from the guys who publish Railroad Model Craftsman magazine mentioned

Home > Carstens Railroad Books > Carstens Model Railroading Books > Traction Handbook for Model Railroads by Paul and Steve Mallery  Item# 013-3 $12.95 About this item Introduction to traction modeling, power distribution, trackwork, design of a model traction system, structures, signals, cars and locomotives, electric control and operation.http://carstensbookstore.com/trhaformorab.html

They also have
http://carstensbookstore.com/trpledbyhalc.html
(missed and clicked quote instead of link for link and now can't figure out how to get rid of quote block, tried highlighting and clicking quote again thinking that might un-quote, nope; tried highlighting and deleting, wouldn't highlight; tried backspacing, nope. Am out of ideas.)
Home > Carstens Railroad Books > Carstens Model Railroading Books > Traction Planbook, edited by Hal Carstens  Item# 00016 $9.95
About this item This Second Edition of the Traction Planbook includes revised and expanded text, plus many new photographs. Drawings are reproduced at either HO or O scale, and depict a variety of equipment from electric lines all across the country. While many electric railway cars were standardized, even the standardized cars exhibited variations such as extra windows, one ot two poles, third rail shoes, door variations, plus differences in pilots, headlights, window grills, dashers, end windows, and more.
A great variety of equipment is presented, from early horse cars and trams, to later wood bodied streetcars and interurbans, to modern steel bodied cars. Coaches, combines, locomotives, freight motors, line cars, and other configurations are shown as well. Streetcars, trolleys, interurbans, rapid transit, freight and express cars are all shown here.
The Traction Planbook is a great research tool for the historian and the modeler alike. From faded classics to modern rapid transit, you'll find it all in the Traction Planbook. 98 pages, softcover. Edited by Hal Carstens.

Did that on HO but on on the G that would prevent using friend's garden layouts.

Have been wondering about possibility of stuffing changeover wiring in to little bitty HLW Sparkys, which use motor block, frame molding and cab from their Mack.

How about this for a G scale garden layout with dummy overhead...use r/c with onboard batteries. Then no matter where you ran your equipment, it would work fine. Just an idea, a crazy idea.

Actually, a quite practical idea. HLW Sparkies are small enough to require batteries be in another car.

Am in these Yahoo groups but I have been inactive for last number of months.
