The central clock dependency is cool, but I wonder is there were any problems with latency -- like does the centralized electrical impulse reach a train station 10km away and another one at 20km at the same time? Did they factor that in?

Isn't that propagating with around the speed of light? Switzerland is only about 1 light ms wide so even if they only have one master clock instead of one per train station the latency should be negligible especially in the 1950s.
The speed of light is copper wires is fast enough that you don't need to factor this in. At least not for human purposes.
I know the Swiss are known for punctuality and timekeeping, but I don’t think anyone is going to notice a 33μs delay to their train.
