Headlight usage

[Flickswagen]

Hello,

 

I'm looking for information the different headlight modes used on locos such as the E186 and when are they used (in real life). The E186 mission only includes the use of one, for driving on the left track, but I'm looking to know what the others are for. Thanks.

Pc1 - All three lights white - Marking the front of a train or other railway vehicle that runs on a single-track route or on the main track on a double-track or multi-track route.

Pc2 - Left light is red, rest white - Marking the front of a train or other railway vehicle running in the opposite direction to the main track on a double-track or multi-track route.

Pc3 - Marking the front of a train with a snow plow

Pc4 - Used when going forward with cars on the front of a train - This signal is used for pushed trains that do not have an active control cabin at the front. One white light is permitted on sidings when driving at night, and without signaling during the day.

Pc5 - Two lights red at the back of a train or portable end-of-train signal dials - Marking the end of a train or other railway vehicle.

Pc6 - Two lights red and upper light white - It is used when, for unknown reasons, a train with a single traction crew (only the driver) stops on a double-track or multi-track route. This signal applies to freight trains. The driver displays it when leaving the cab to determine the reason for the stop. The driver coming from the opposite direction should, seeing such a signal, stop his train and help the driver of the train displaying the Pc6 signal.

Tb1 - Front right light white and on the rear left light white - Designation of the front and rear of a traction vehicle moving in shunting mode. One white light should be on on both fronts on the side of the occupied driver's position

Signal A1 "Alarm" - It consists of two flashing white lights on the front of the traction vehicle and simultaneously one long and three short siren sounds. This signal is used to notify railway workers of an existing or possible danger. It should be administered until the danger disappears.

 

These are the most important lights signals used in Polish railway.

Thanks both for your replies. I've read the signs and signals guide before, I seem to have missed the part about the headlights.

I have a somewhat related question. Here in Estonia, we have similar headlight arrangements on trains, dating back to the Soviet Union I believe. Usually, a parked train shows one red light at the left side of both ends, looking towards the train. However, I saw one train which had two upper red lights illuminated, which I hadn't seen before. Would anyone happen to know the reason for this?
