The Stuttgart Rack Railway (German: Zahnradbahn Stuttgart) is an electric rack railway in Stuttgart, Germany. It is the only urban rack railway in Germany, and one of only four rack railways operating in Germany, along with the Bavarian Zugspitze Railway, the Drachenfels Railway and the Wendelstein Railway.
Affectionately called Zacke (spike) by the residents of Stuttgart, the line was opened on 23 August 1884. It connects the urban districts of Stuttgart South (Marienplatz) and Degerloch (Albplatz). The route runs along the Alte Weinsteige, which was historically the main route to the Filder towns until the Neue Weinsteige was built in 1826.
Over its 2.2-kilometre (1.4 mi) route the line climbs a height of 205 metres (673 ft) (from 260 to 465 metres (853 to 1,526 ft) AMSL). The maximum grade on the route is 17.5% (7 in 40) (between Liststrasse and Pfaffenweg). On the branch line to the depot of the (old) rack railway yard, the maximum is 20.0% (1 in 5). Between the stops at Pfaffenweg and Wielandshöhe there is a view of Stuttgart's city centre.
The rack railway is integrated with the metropolitan railway network of the Stuttgarter Straßenbahnen AG (SSB) as Line 10. At Marienplatz it connects with Stuttgart Stadtbahn lines U1 and U14 and at Albplatz it connects with lines U5, U6 and U8.
The line is one of two working railway lines that are tourist attractions in Stuttgart; the other being the Stuttgart funicular railway that leads to the forest cemetery, and operates as SSB line 20.
The rack railway cars includes a trailer at the front or back for transporting bicycles.
