In the metro, there are many signals and signs that you must recognise and obey for safe and efficient operation of the train. Failure to respect them could result in delays and inconvenience for the passengers and, at worst, a health and safety risk.

The ARS/ALS systems will aim to prevent the most dire of scenarios such as collisions and derailments. Brakes will be applied if the train exceeds the speed limit, and emergency brake application will be forced on if the train passes a red signal.

Important:Disabling the relevant safety mechanisms is strictly forbidden and will result in unconditional termination of the driver's license on ranked servers.


Signals

Track signals are used to regulate train traffic and ensure safety of all trains, staff and passengers. Take time to memorise the signals and their meanings.

Standard signals

One red light: Stop! Driving through is prohibited. red.jpg
One yellow, one red light: Stop! Driving through is prohibited. yellow-red.jpg
One red light, "OP" ("ОП"): Tracks and dead ends are terminated with one red light and a "ОП" (опасность/opasnost, danger) sign. Do not cross under any circumstances! red-op.jpg
One flashing red light, "DOP" ("ДОП"): "ДОП" (добавочный опасность/dobavochnyy opasnost) means "additional danger". This indicates that there is a temporary change to the track configuration which should be treated as a dead end. For example, if a track switch is in the wrong position as you approach a merging junction, as it would derail the train when passing over it. flashred-dop.jpg
Red signal with KGU (КГУ): The KGU sensor detected oversized parts of the train. ИСИ Метрополитен 88.jpg
