Lighting the Turntable...

I had some fun in the laboratory the last couple of nights.  I figured out how to wire the lighting to my Walthers Turntable.  I tell you, this thing is a beauty.  My first issue was getting power to the lights on the bridge.  I decided the easiest thing to do  would be to pull it directly from the track.  Since I run DCC, there is a constant 14v AC running through the rails.


I used the brass rod to run under the walk boards to the solder blob that connects the factory power connection. These run to the outer edge of the walkboards where they are soldered to the rods that run the length of the bridge. You can also see the mounting of the two side lights on the overhead structure.  The lamps are N scale lamps and shades by Miniatronics, with the bulbs rated at 1.5v.  A resistor is needed for each bulb.


You can see the brass rod running the length of the bridge. There's one on each side to feed power to the lights.


Here you can see a close up of the connection of the resistor to the brass rod, and the rod rising through the deck to make a lamp post.  I painted the rod and resistors charcoal grey, so they look like conduit and misc. equipment that might be found on the side of a turntable bridge...


And a look at the finished product.



I never thought I'd see the day when I would gleefully tear into a $250 model with a drill and a soldering iron!

Lee that is fantastic. You amaze me with your work sometimes!!

So, n scale light, shade, brass rod, resistor, and solder?
that about it?
Jesus is my engineer! :)

You'll also need a skinny drill bit and a pin vise.  But, yeah, that's about it.  The whole job took about an hour.

There was some discussion on using one resistor for the whole shebang , or 1 per bulb . What did you wind up choosing to do ?

One per bulb.  I tried putting one resistor in then wiring the bulbs in parallel, but that didn't work.  Fortunately I had plenty of resistors floating around the junk box.

Note to self:
In the future, do not waste your time explaining to Lee why he shouldn’t wire something as he is planning, because he is not going to listen and will do it anyway.

It's not that I wasn't listening, I got more than one bit of feedback, and everyone was certain that theirs was the right way to do it... it just happened that yours actually was!  Thanks ;D

Looks great Lee!
Now seeking Pacific NW N scalers to create a Modutrak-style modular club featuring NP's shared mainline between Seattle and Portland. PM me if interested.

That is an absolutely beautiful effect, Lee!

Please, keep up the good work--I'd love to see that kind of nighttime lighting on a whole engine facility.

I once had plans to put lights on my North Sheldon half-module, but the Cow Palace at Timonium isn't quite dark enough to make lighting the module worthwhile. Almost dark enough, mind you, but not quite. :)
