Gentle Breeze Railway
07/15/23
Work on the Gentle Breeze Model Railway started more than 10 years ago. I regret that I did not keep a journal at work so I am starting now with the Gentle Breeze Railway on the OGR forum. It will take multiple entries until I have caught up with my progress to date. I am a slow writer and it is easier to have shorter updates. I have retired and just started the actual construction. The first 10 years were building the Train Mansion (My wife’s name for the building stuck), designing the layout and developing the electronics and software. The Train Mansion shown in the picture is two 30’ x 40’ stories. The top floor has a bathroom, small kitchen, pool table, pinball machines and storage racks of trains. The lower floor is the home of the Gentle Breeze Railroad.
The goals of the Gentle Breeze Railway are:
- Trains controlled by people and/or scheduled or random computer control.
- 30’x40’ around the wall layout with a double mainline
- A yard with a turntable, city, town and rural.
- Turnouts controlled by touchscreen and/or computer.
- Manage the costs.
- Stretch goal to operate a model train like a real engineer with video from the engine and properly working ABS block signals.
Layout Command Control, LCC
8/18/2023
Layout Command Control, LCC, is an open source NMRA standard for controlling layouts. The NMRA describes LCC in the following way: “Model railroaders expect a lot from the electronics on their layouts. They want to automate accessories, simplify operation of their staging yards, have fine control over layout lighting, and build realistic dispatcher panels. Home and club layouts are getting more detailed and complicated, and existing electronics for control systems are having a hard time keeping up.” Random running of trains requires knowing the location, direction and speed of the trains. In my evaluation of block occupancy methods I chose LCC. LCC is the most efficient, scalable and cost effective way to monitor occupancy, control turnouts, block signals and accessories. LCC nodes all have significant compute capability and use the Control Area Network, CAN, bus for bidirectional communication. The CAN bus is used by the electronics and cars and trucks. The predominant CAN physical layer used by LCC is ethernet cables.Excellent presentations on LCC can be found here. https://www.rr-cirkits.com/Clinics/Clinics.html. The LCC network is a very efficient method to transfer block occupancy information to Traincontoler or JRMI. My first priority was computer controlled random running of trains which require block occupancy. With block occupancy the next step is accurate block signals and crossing gates. The rr-cirkits “Signal LCC” nodes have enough compute power to implement complex prototypical ABS signals.
