G'day Dmitriy,
Cyrillic characters are awkward, as are any character accents, for my humble computer.
I hate to think how complex digital communication would be in Chinese and Japanese.
The Russian signal system intrigues me.
As does any railway signal system.
I am also curious to know how long ago, that the Russian railway removed the "brake van" (caboose) from the rear of freight trains.
Here in NSW, the guard's van was gradually removed from freight trains from 1986.
Steve.
