Take a tour of the 36"x80" N Scale PRR! The layout is based on a fictional segment of the Pennsylvania Railroad's Middle Division between Harrisburg and Altoona, PA, in July 1956. The layout is operated with Digitrax DCC. Music is by Hans Zimmer, from the Simpsons Movie soundtrack.
Here we see the Logic Rail Technologies Signal Animator in action at LEW Tower. As the train passes over the optical sensor, the signal "drops" from Clear to Absolute Stop.
The boys enjoyed spending the afternoon playing in the sprinkler. They enjoyed the pretty rainbow, too. You can see my garden as of late April, too...full of greens.
