Tomytec Bus Automation

For more than a year now I am trying to control the Tomytec busses (fitted with a BM-01, BM-02 or BM-03 motor). My ultimate goal is to make the street at the centre of my layout look like this:

There will be

• Two bus lanes (one in each direction), with busses following each other and queuing at the bus stops and traffic lights.
• Two car lanes, with all cars stopped because of the traffic.
• The tram lane at the middle.

I have made significant progress in the past weeks and I am now able to

• reliably detect the busses using hall sensors (placed just below the guiding wire)
• stop the busses using electromagnets on the right side of the guide wire (the Tomytec busses detect the magnetic field and stop until it is switched off).

Under the bus lane, I will place “bus block” control units (I have built twenty of them so far) wherever I want the bus to (potentially) stop. This is what two bus blocks look like (seen from the bottom):

They will all be connected to a Raspberry Pi, which will be able to control the traffic flow.
All of this is still under development, but this weekend I have been able to connect eight bus blocks, and this is the result (that I find really encouraging):
