RAILS is a software model and implementation of an automated system to assist the model railroader achieve realism in the operation of a model railroad. The model then drives the development of software.
Cntrlr Turnout is an open-source printed circuit board by djbristow, from the djbristow/RAILS repository on GitHub. It is a 2-layer board of 137.5 × 78.5 mm with 12 parts on 55 nets, routed with 212 tracks and 8 vias.
It is built around the L293DNE and MCP23017-E/SS. Its parts include 4 capacitors and 4 ICs. It belongs with the ESP8266 boards of this library.

It measures 137.5 × 78.5 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the L293DNE and MCP23017-E/SS. 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.
From the djbristow/RAILS repository on GitHub, at the commit this page was made from: the board is Microcontrollers/Turnout-Cntlr/Tortoise-Turnout-Cntlr/Hardware/Cntrlr-Turnout.kicad_pcb and its schematic Microcontrollers/Turnout-Cntlr/Tortoise-Turnout-Cntlr/Hardware/Cntrlr-Turnout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask djbristow before reusing the design.
