Cossonay–Gare–Ville funicular, Funicular railway in Cossonay, canton Vaud, Switzerland.

The Cossonay funicular runs in a straight line for 1,219 metres between Cossonay-Penthalaz station, about 50 metres west of the SBB platforms in Penthalaz, and Cossonay-Ville, just southeast of the old town next to the Hôtel du Funi. It climbs 133 metres at gradients of 100 to 130 per mille on a single 1,000 mm gauge track, with an Abt passing loop at the midpoint. Two cabins, each holding 60 people since the 2021 rebuild, counterbalance each other on a 19 mm haul rope.

Built in 1897, the system originally relied on water counterweight to move the cabins up and down the slope. A major rebuild in 1982 switched it to electric power, which continues to operate it reliably today.

The lower station, called Cossonay-Gare until December 2014, stands in Penthalaz, not in Cossonay; it was renamed Cossonay-Penthalaz (funi) when the SBB station changed name. The upper station sits beside the Hôtel du Funi on Avenue du Funiculaire, just southeast of Cossonay's old town centre.

The line runs daily from 5:00 to 0:40, usually every ten minutes and every eight minutes at peak times. The lower station stands about 50 metres west of Cossonay-Penthalaz railway station, across the Route de Gollion; the upper station is just south-east of Cossonay town centre, beside the Hôtel du Funi on Avenue du Funiculaire. The track is straight apart from the passing loop at mid-slope.

Because the gradient is relatively gentle, the line has an underslung cable in addition to the haul rope, linking the two cars beneath the track via pulleys in the lower station. The passing loop uses an Abt switch. The upper station stands beside the Hôtel du Funi on Avenue du Funiculaire.
