The Semafor application enables quick and easy access to descriptions of signals displayed on semaphores and signaling devices. Thanks to this application, you will learn about the signals on the Polish State Railways, wherever and whenever you need it.

Convenient and friendly interface will allow you to display any signal that interests you at the moment. Virtual semaphores represent a specific signal, an appropriate definition for it, a description of the place where the signal occurs and the speed at which you can move around it. In addition, the application contains a successively updated database of indicators used on Polish Railway Lines. All descriptions comply with the Ie-1 (E-1) 2020 signaling instruction.
