The back drop painting has been completed. Marilyn picked the basic blue color for the sky. We collected a number of cloud pictures (some we took ourselves) so the artist could see the type of cloud formations we wanted.

We included a storm with a lightning strike and sun rays though a cloud. It is pretty neat with all the variety of clouds.

I decided to design my own circuit breaker. At this time there are some good commercial circuit breakers available. However, none of them had all the features I wanted. Low cost, remote on/off control and off at power on to name a few. Low cost was important because I want to use a lot of them. In some places like yards and sidings I want to be able to turn off power and the short circuit protection is not the main requirement. If there are a number of sound locos that are not being used, it is nice to be able to turn off the sound.

Designing the breaker was not as easy as I though. There is a trade off of being able to turn off power fast enough when a short occurs to keep the booster from shutting down and not turning off power when there are a number of sound locos on the track. Sound locos and passenger cars with lighting tend to have large capacitors. Capacitors look like a short circuit when power is first turned on.
