For now, only the railway signaling is available in English.


If you don't know the basics of european railway traffic, better check the site of Prof. Dr. Joern Pachl. In Bulgaria we have almost the same rules, excepting the block instrument principle.

The meanings of station (with the home signal limits), open track, train and shunting movements, points operator, train director (known here as pointman and movement director) are the same.

The exact bulgarian principles are not available in English yet.


All signals are at the right side of the track, but there are three exceptions:

 - The signals for the wrong or left track on double track lines can be at the left side, but only if there are no other tracks there. No special signs are required for the left-sided signals.

 - Hand signals can be given at both sides;

 - Speed restriction end signals are always at the left side, excepting the right track on double track lines (only when there are no other tracks there).


If you have some knowledge of the european railways, may be you will try to find something about Indusi or similar system. Don't try, you'll find nothing.

It's possible to be strange for some readers (and it is really strange), but in Bulgaria there is no such traditional thing like Indusi, or the french Crocodile, or other similar system.

Nothing will stop the driver to pass a red signal at danger at 120 km/h or more.

Without Indusi system, there is no practically need of overlap distance behind the signals, so we have no overlaps.

With no overlap, the shunting movements are allowed up to the opposite home signal (no special shunting limit board).


Only the mainline Sofia - Plovdiv - Bourgas is equipped with some kind of ERTMS level 1.


The braking distance used in Bulgaria is usual 1000 or 1200 m, but also 700 m for some branch lines, 1500 m on the new line in construction Plovdiv - Svilengrad and 400 m on the narrow gauge line (760 mm) Septemvri - Dobrinishte.


Almost all signals are already checked here. Hand signals, sound signals and signals of movement director (with his order disk) will be described later.
