John....

Even your construction photos with a ladder in it show what a cool RR you are building.

On the S&S RR the steam whistle is used to signal other facilities  on the sprawling Eagles Nest complex.  Especially important, lunch and end of the shift.

That's what I figured it was for, and why I thought it should be mounted outside of the building so everyone can hear.  It's my recollection that steam sawmills had whistles for the same reason (plus to alarm everyone in case of fire, a common occurrence in sawmills!)

My time frame is 1949 so the only electronic communications would have been a telegraph in the mountains. After having my Grandson's here for the weekend, last weekend, I may just find another use for a steam whistle.  It involves light screens and fingers reaching in where they are not welcome. Just a thought. I'm actually looking into a button activated steam whistle for the boiler that the kids can push. If I remember correctly Slim has just what I need.

Thanks for the complement. It should also be noted that the bump hat on top of the ladder is one of the most important tools when working both above and below the layout. That bump hat has a number of scares that I would have had on my head.


That picture was taken with circuit 3 turned off. My layout room has 4 - 20 amp power circuits in an auxiliary box so I can turn off the power when I'm working on it without turning the power off for the rest of the house. The boss and CFO of the S&S RR likes that feature. When I designed it LED lights were not available, I could power the whole thing with one now - but it is nice to be able to turn off 25 % of the lights when I'm working on it.

I know that LED strips will not operate off of a common zero up rheostat.  But they can be dimmed with a timer device that runs a variable on - off ratio.  Like a 555 timer chip up to a darlington pair transistor that will take the current load.

Have you considered something like that for a dusk setting?

Thus thinkin' out loud...

The LED lamps that I'm using are supposed to be dimmable but I haven't tried it yet.  I'm not using the LED strips but replacing my incandescent lamps with LED lamps. I like having the option of putting the light right where I want it.  It should be easy to implement your idea - just replace my switch with the proper dimming switch. A future project.

For strip LED  lights there are a lot of neat solutions. Take this item for example: https://www.flexfireleds.com/juno-bluetooth-smartphone-single-color-led-dimmer/


If you're using LED floodlights that screw into regular 110V bulb sockets then dimable versions of the LED floods coupled with a LED compatible dimmer will work.

Ouch! Slim has lots of good correct answers. My fault for being brief.

No apologies Dave. 

That was really funny.

Hey John:

Looks great so far. Nice job on the boiler.

Slim I'm working on an order for the sound circuits we talked about. I will be getting in contact with you with questions.
