Getting back to HO model trains after taking a 45 year break. Working on a new automated Christmas layout... Hogwarts Express with lighted carriages, sound, Platform 9 3/4/Hogsmeade station/Hogwarts, turntable, a little shunter, voice controlled by Alexa, run by a Raspberry Pi with wifi track sensors. Hoping for some technical DCC-protocol help. I this all works reliably, which is somewhat unlikely, I will make the software available.
