Questions
How big is the Rail Power PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rail Power use?
31 parts, built around the LM317AG-TN3-R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Rail Power KiCad files?
From the acwright/Wright-Train-Works repository on GitHub, at the commit this page was made from: the board is Hardware/Rail Power/Rail Power.kicad_pcb and its schematic Hardware/DCC Decoder Shield/DCC Decoder Shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rail Power design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
