Woo - that is impressive.  
Here's a link to a Block-Signalling system I created 2-years ago using Finite State Machines (FSMs).

> Got a bit bored this afternoon so I knocked-up this demo flow. It has a finite state machine (FSM) for each of the 6 signals and an animated slider to mimic a train journey. To keep things simple there is only one buffer block (caution block) - you can obviously modify that by introducing additional blocks and signals. BOD means Block Occupancy Detector. Hope you find it useful. The Node-RED flow is below as together with the screenshots it …
