to give a idea.
In the need for electronics? please let me know, cous that is quite a list.
Igor,
I ordered 20 pcs P1560B and got them a few days ago! No problems with customs.
The pins are 2,5 mm diam and at the shortest 26,7 mm and the longest 34 mm , so the shortest will easily fit between the wheelaxis and the sleepers.
The max force to push them in is about 3 Newton (0,3 kgforce).
So lets assume with 4 wheels all active hitting with 4 pins on a sleeper a vertical weight of 1,2 kg should be needed to prevent the whole uplift of the loco.
I designed the wheel that holds the 8 pins using two halves that will contain the 8 pins.
This wheel will be fitted to the loco wheel with 4 screws.
This is a 3D view of the 2 wheel halves
This is one of the pins from Ali-express at max length
