N-gauge Japanese-style Model Train
The trucks and vans are from
I decided to rebrand and expand the small truck terminal (Tomytec 069-2 Modern Truck Terminal). The expansion is done using Greenmax 2187 building kit, which is extremely flexible and easy to customise.
This is the first stage of the construction.
Two years and five months ago, I managed to control a Tomytec bus by using an electromagnet under the road. I am now happy to report that I have finally been able to move the modules of the main street, bus interchange and Iwasehama station to the layout. All the wires for the bus control blocks, the hundreds of LED lights, the signals and the tracks are connected and everything seems to work fine. Well, not everything. There are still so many things to improve. These buses sometimes seem to have a mind of their own!
Next (major) step: finish the tram layout, and make sure that trams and buses don't collide! For that, I'll have to teach the Raspberry Pi Python application controlling the buses to talk to Rocrail! Interesting challenge.
In this first test, I used a 13x27 12V 1W 10N (size 13x27mm, 12 volts, 1 watt, 10 newton force) electromagnet that can easily be purchased from AliExpress (look for solenoid, electromagnet, or follow this link). Its power consumption is about 100mA, which is reasonable, and the heat dissipation is not too high.
The bus stops when the electromagnet is powered, then restarts when I switch off the power supply.
