There is a solder available that is 95% tin, 5% silver which is much stronger. than the common stuff. Been using it on overhead for about 10 years now.

Two foot----For me, the wire is tighter in the Summer, because the layout "room" is a 40' aluminum insulated trailer, that is 3/8" longer in the Summer, due to it expanding from the heat, and the layout is fastened to the walls.

Temperature will change the geometry of the overhead a bit. Right now I'm using NMRA trolley poles which are way over sized but track really well, so I'm not having any problems yet. But when I start using the more finer poles, I'm sure i'm in for a lot more tweaking and adjusting.
I belong to the Southern California Traction Club which has a large modular layout. Temperature makes a difference with a layout that large. We'll be running fine for hours, but suddenly we'll start suffering frequent dewirements. So temperature is something to watch out for.

Great track work and overhead wiring. A lot more patience than yours truly Dandy.
Dewirements sounds just like our trams here in the city of Melbourne.
Although the folks that decided to keep our trams must be chuckling in their graves as they move a hell of a lot of folk in our rapidly growing city.
Looking forward to reading your blog.
Rod.

That's not only a great build, but a fun video, too. The music is great, as are the camera angles. Thanks for the fun!

Impressive work, Dan, impressive. :bow:

Looking forward to your Gas Lamp Quarter construction, what time period will be using ? And, will the San Diego Hardware store be on the layout ?

Thanks Wayde!

I actually purchased some material for the layout from San Diego Hardware.
Unfortunately, my city blocks are really small. So I'm limited to only modeling corner buildings whereas SD Hardware is a midblock building. BUT, SD Hardware's original location was between the Backesto and the Old City Hall buildings on 5th, two buildings I'm including on the layout. So I could include it there!

As for the time period of the layout, well... this will explain it:

What a great idea! And if you incorporate it later nto a larger layout, only possible modification might possibility be to some of the "newer" streets if you decide on an earlier era.

I know this topic is almost a year old, but I just had to comment anyway. I've seen Dan D. Sparks' Grand Union Intersection in action at his website which I like to visit every now and then. I've watch the video there showing the Grand Union Intersection and it is a masterpiece. I am amazed by the web of overhead wire above the HO scale trackage and by how smoothly the streetcars run through the entire intersection without dewiring. I find this really fascinating - and scary, too. If it took Mr. Sparks 30 years to get this overhead wire project working right - then it should take me a hundred and fifty years just to get the trolley line poles setup on the layout. I'd hate to think how much longer it would take me to get the overhead wire in place.

Someday, I'll get around to building a traction layout - but I'm going need a lot of help when I do.
