Merkurbergbahn, Funicular railway in Baden-Baden, Germany

Merkurbergbahn is a metre-gauge funicular railway in Baden-Baden, Germany, running 1,192 metres up the Merkur to a summit station at 657 metres, eleven metres below the 668-metre peak. Its two automatic cars each carry 38 passengers and climb gradients of 230 to 580 per mille. The pale green valley station has a gabled facade, a large arched opening with a fanlight, and a sign reading "MERKURBERGBAHN".

The Merkurbergbahn opened on 16 August 1913, built by Maschinenfabrik Esslingen for 251,000 marks after R. Holzapfel's 1907 study recommended an electrified funicular. It closed on 1 November 1967 for safety defects and reopened on 27 April 1979 after a major rebuild, becoming automatic and driverless. Between January 2019 and June 2020 it was renovated in stages, with barrier-free stations and new cars and drive technology.

The funicular serves as a gateway to outdoor activities, connecting visitors to hiking paths and observation platforms overlooking the Black Forest region.

The ride takes about five minutes, not fifteen, for the 1,192-metre route with its 370-metre climb. Since 1979 the cars run automatically and are operated by passengers like a lift. Both stations were rebuilt barrier-free between January 2019 and June 2020, and city bus lines 204 and 205 end at the valley station.

The line's steepest section reaches 54 percent, and the two cars each carry 38 passengers. Since 1979 the railway has run without a driver, operated by passengers much like a lift, and on busy days it carries up to 3,500 people, among them many paragliders.
