1. An LED light fixture that is removably mountable to a mounting bracket for providing pathway light for a train tunnel;
- the mounting bracket mounting the LED light fixture to a vertical wall to provide downwardly-directed light for the train tunnel;
the LED light fixture comprising;
an LED light engine;
a battery backup system that includes a backup battery;
an LED power supply being powered at a high voltage and outputing a low voltage direct current for powering the LED light engine;
a quick connect power connector that allows the light fixture to be readily replaced; and
a housing that carries the LED light engine, the LED power supply, and the battery backup system;
the housing having a bottom and carrying the LED light engine within the housing in a position to shine light down from the bottom of the housing when the LED light fixture is mounted to the mounting bracket on a vertical wall to provide track bed lighting.

Abstract
A light unit used in train tunnels is readily mountable and removable from a mounting bracket. The mounting bracket allows the battery backup system and light engine to be gravity mounted in manner that allows for quick and easy mounting and removal while also resisting vibrations and wind. A quick disconnect fitting can be used with the power cord to allow the units to be removed and replaced as needed. The light unit integrates the light engine with a battery backup system so that the entire light and battery unit is removed and replaced when necessary.
