Could you put the lives or health of several people at risk by ignoring a stop while driving over the railway tracks at this point?

Yes. By crossing the tracks without stopping at a place marked with a B-20 STOP sign, you can put many people's life or health at risk. A collision between a vehicle and a train is almost always tragic, because of the huge mass and speed of the train. The duty to stop comes from Art. 28 para. 2 of the Road Traffic Act, and ignoring it can cause a disaster with many victims.
