Bahn long-distance service, the city is well connected by train. The Franconia Railway (Frankenbahn) connects Stuttgart and W�rzburg, the Neckar Valley Railway and Elsenz Valley Railway run from Heilbronn to Heidelberg and Mannheim, and the Hohenlohe Railway accommodates travel to Schw�bisch Hall via �hringen.
The Heilbronn and Karlsruhe Stadtbahns provide a connection all the way to Karlsruhe on the Kraichgau Railway's tracks. Currently the S 4 takes travellers from Karlsruhe through the central train station past the centre of town all the way to the �hringen borough of Cappel (since December 11, 2005). Because of massive delays in the construction of the S-Bahn tracks through Heilbronn's city limits and with the modernization
and electrification of the existing tracks from Heilbronn to �hringen meant that the new section's official opening needed to be postponed several times. In the future, additional S-Bahn lines are planned to Neckarsulm, Lauffen am Neckar and Zaberfeld. As well a these new lines, additional stops will also be built in the inner city of Heilbronn.
Whilst the original Stra�enbahn of Heilbronn, nicknamed the Spatzenschaukel (German for "sparrows' swing"), was discontinued on April 1, 1955, the city used electrically powered trolley buses until 1960. Today, public transportation is provided by the S-Bahn that runs through Heilbronn similar to the Karlsruhe model and this is complemented by buses run by the Stadtwerke Heilbronn (Verkehrsbetriebe) and several other enterprises. All now belong to the Heilbronner Verkehrsverbund.
The canal port on the Neckar is one of the ten largest German interior ports.
In the industrial part of Heilbronn EnBW AG runs a large powerplant that is powered by coal. Its two chimneys (250 m tall) and cooling tower (140 m tall) are visible from afar, see Heilbronn Power Station
The public tram and bus system is run by HNV (Heilbronner Hohenloher Haller Nahverkehr)
