Got radio working. JMRI on laptop connects to RF-Nano (Arduino nano clones with integrated rf24 radios) via serial using CMRI protocol. Nano then transmits data to the other RF-Nano using the RF24 Network library. From there it actuates the turnout with a regular motor driver.

The idea being that I can distribute these around willynilly and only need to power them, no data wiring required. Next I'll have the same unit transmit sensor data in the opposite direction.
