working marker lights

[Southwest Chief]

Nice work with the class lights.  Tough to do in small scales.

Now, if I could only figure out how to  do that with the microscopic railroad "handlans: used on my HOn3, K-27's and K28's....Hmmm.

They are easier to do in G scale

You can do yellow with this as well. Just the combination of colors.

I solved the front lense issue, 2 smaller fibre optic threads, one for each lense, using heat to flatten the ends it seats well on the marker.

Now I know how what to do its easier now,

Era and prototype will affect marker colors. The Rio Grande still used yellow instead of green until about 1940.

Very nice work with the fiber optics, BTW.

caboose markers would get more complex as they can designate which track, type of train, etc combining red and green lenses, right now I don't know how to deal with different colors on side and rear unless we have dual color super tiny LED's.

(I will call them markers, flags perform the same function)

Nice work on getting the right colors for those CLASSIFICATION lights.

Now, when to use which.  For TTTO operation:

1. Train running on timetable authority, and last section of train running in sections - dark.
2. All but last section of train running in sections - green.
3. Extra (Train not on TT, authorized by TO) - white.

The only time a loco-front classification light should show RED is when the locomotive is working tender first as a rear-end pusher, or running light tender first.  (The tender than has to display appropriate classification lights.)

Fun, isn't it?

I've always wanted to enhance the operating environment, and put it to the test on a featured model. That model is a Nickel Plate products NKP Hudson. As if I already got the mars and headlight working on it, next step is working marker lights. Here is a progress report.

Using a Titan decoder (but you could use any function decoder or a decoder with at least 3 separate lighting functions)

Then using a 3 color superbright LED (designed for RGB large size TV's) I can get the 3 basic marker light colors, White, Red, Green.

The marker lights on the hudson presented a problem as they are mounted on the elephant ears. The solution, fibre optics.

At the moment only the side illuminates, but I will experiment, notching the fibre and insert a fibre for the other direction, that should divert light for the forward direction.

Look ma no hands.

On the titan I have to program it to change colors, but a simple function decoder is just button presses (when setting up the decoder)

The Titan uses "addressing" CV's, it takes 2 (or 3) CV's to set a function feature.

But once you have the addressing set, changing the colors is a snap.

It took me some figgering out how to do this on the Titan but thats how, using front/rear markers and rear number boards lighting functions.

Once I finish this its lighting the front number boards, (a trick I already did on an AHM 2-8-4)
