Buffer lanterns are light - signal devices located on the buffer rail of a rolling stock. Together with the marker lights and the locomotive searchlight fire, they are intended to designate the head or tail of a train , single locomotives , and running track machines . Usually have transparent white and red lights; other signal colors (for example, yellow) are shown using a color filter mounted on a white light.

History
Since the advent of the railways, kerosene lamps have been used as light-signaling devices on railways, giving yellow-white light. Red and green colors were obtained with the help of colored glass mounted on the lantern. The yellow color was not used, as it was difficult to distinguish from the natural color of the kerosene lamp fire.
For the installation of color filters in front of the windows of buffer lamps, special pockets-holders made of wire in the form of a triangle or Y-shaped [1] were provided. In the same pockets were installed and blackout slot masks.
With the advent of electric incandescent lamps, it became possible to control the lights of buffer lights from the cab, which made it possible to abandon the use of fragile and impractical light filters by installing separate red buffer lights. However, many locomotives ( steam locomotives , early diesel locomotives, and electric locomotives ) still used single white buffer lights and plug-in light filters. On some locomotives (for example, diesel locomotive CHME3 ) the red lantern is installed in the same hull with white [2] [3] .
In recent years, there has been a transition to the use of LEDs in buffer lamps instead of incandescent lamps (as in other light signaling devices — for example, traffic lights ).
Signal readings from buffer lights on railways of the countries of the former USSR
Rolling stock designation
- When driving on a single track and on the right track on double track sections, the head of the train day and night is indicated by two transparent white lantern lights at the buffer bar and one transparent white spotlight fire.
- The tail of the train when driving on single track and on the right and wrong path on double track sections is indicated:
- passenger and post-baggage day and night - three red lights : a red light of the buffer light on the right side and two upper position lights.
- the tail of a freight train or a single locomotive is the red fire of the right buffer light.
When moving cars forward at night, the tail of the train is indicated by two red lights on the locomotive buffer bar [4] .
Alerts
- Two red lights buffer lights - "There is an obstacle for movement on an adjacent path" [5] .
