I have plenty of track and switches to build the plan. Are there issues I should be aware of with respect to wiring, cleaning, utilizing very old switches, the single arm/single blade catenary, loks and running stock? Most of my running equipment is from the 60's through the early 90's; will this be problematic? Should I just think in terms of using the old track as I would stud M Track? I'd appreciate any suggestions you might be able to offer. Thanks. Dave
Hello Dave and welcome aboard!
Great project and excellent idea: retirement is the time to make dreams come true.
There is no special consideration using solid center rail track, except that you are dealing with old equipment and sometimes a little oxidation is unavoidable.
For cleaning, refrain from using any sand paper or abrasive.
I use lighter fluid (but carefully!!) on a rag to wipe the tracks before mounting them.
After that, the regular running of trains is all you'll need to keep it operational.: it removes the crud quite rapidly
In terms of wiring,I would suggest you feed your track every 3 to 5 sections (both power and ground!)by soldering a wire to the connecting tongue.
It may seem a little overkill, but please take this as the best piece of advice I can give to avoid/reduce frustrating debugging after all the track has been anchored down!
Another word of caution: the old catenary masts can be very fragile, as they too suffer from the dreaded zinkpest.
I suppose you are aware that until about 1951, the switches had single coil motors, (acting a bit as a flip-flop)and require 24 Volt supply.
They are recognizable by the fact that they only have two wires: one yellow for the lighted lantern and one black with a green plug for the supply.
Same apply for signals and uncoupling tracks of the same vintage.
Newer switches and signals have double coil motors and are recognizable to the three wire: one yellow and two blue.
These will allow you to build up a simple automated block system, which I always thought was the coolest thing on earth when I was a kid in the 1950's (I am still a kid, but now in the 2010's....

)
And if you discover problems with old rolling stock, you have come to the right place, I don't think any of your questions will stay un-answered for very long!
Once again welcome
