Alstom APS, also known as Alimentation par Sol or Alimentation Par le Sol (which literally means "feeding via the ground"), is a form of ground-level power supply for street trams and, potentially, other vehicles. APS was developed by Innorail, a subsidiary of Spie Enertrans, but was sold to Alstom when Spie was acquired by Amec.
Vehicles and pedestrians are free to move across the APS rail between the rail tracks, as segments of the rail are powered only when there is a compatible vehicle covering them. Alstom APS uses a third rail placed between the running rails, divided electrically into 11-metre segments. These segments automatically switch on by radio control only ...
Alstom has developed a ground-level power supply (alimentation par le sol - APS) system for use with buses and other vehicles. [120] The system has been tested for compatibility with snow plows and for safety under exposure to snow, ice, salting, and saturated brine. [121]
Central rail of the APS system. By demand of the Municipality of Bordeaux (CUB), part of the system uses the Alstom APS system of ground-level power supply. There is no overhead wire, and electric power to the tram is supplied by a segmented center rail. Only the segment directly under the tram is electrically live.

Alstom APS was the first modern commercial ground-level power supply system, first installed commercially in Bordeaux. [8] [9] The French government reports no electrocutions or electrification accidents on any tramway in France from as early as 2003 [10] until as recently as December 31, 2021. [10] [11] [12]

Instead, Alstom has equipped approximately 80% of the line with its proprietary ground-level power supply (APS) system. The remaining 20% uses on-board supercapacitor-based energy storage (SRS), also developed by Alstom. [6] Trams are still equipped with pantographs for use in the maintenance facility.
