About :

In this material I will show you practically why a signalman or a signalman has to lock a switch. I will tell you what this lock is, what it looks like on the ground and what is used to lock this switch. I will also make a short introduction to schematic plans and show you the markings that always appear on them and explain the difference between them. I invite you now and soon even more curiosities :)
