In the late 1990s Volkswagen decided to assemble cars in a glass-walled factory in the middle of Dresden. Every car plant lives on a river of inbound parts, and that river is normally trucks — but this factory's whole premise was that the city could watch it work. Running convoys of diesel trucks through the baroque centre would have broken both the streets and the story.

The answer was the CarGoTram. The first tram entered test service in October 2000 and a second followed in January 2001: purpose-built freight vehicles designed around Volkswagen's cargo, sharing the tracks of Dresden's passenger network. The plan set out in the trade press at launch: 21 hours of operation a day, and at full build-out 36 trips a day, each a 40-minute run between the Friedrichstadt logistics centre and the factory at Straßburger Platz.

The hand is that nothing new had to be built. The rails, the right of way, the maintenance and the traffic discipline already existed for passengers; a freight slot on top of them was a timetable problem, not a civil-engineering one. When researchers later reviewed urban freight by rail, Dresden stood among the four implemented European cases — Amsterdam, Dresden, Paris and Zurich — and the verdict was that the concept is feasible because it cuts congestion, emissions and traffic in the city.

Run freight on the passenger tram network

The rails already reached everywhere the trucks would have had to force their way through, so using them avoided new rights of way entirely.

The tracks were built and maintained for passenger service, so the marginal cost of a freight slot on top was small compared with any road scheme.

A tram through the centre matched the product: a factory built to be seen could not trail truck convoys past its own windows.

The vehicles were purpose-built for Volkswagen's cargo rather than adapted from passenger stock, so capacity was not an afterthought.

If your problem is the last kilometre through a protected city, borrow infrastructure that already has the right of way. Freight on a passenger network turns construction into a timetable.

The Dresden tram became the reference implementation for urban freight on light rail: when the trade press reviewed the field in 2017 it was the long-running example, and cities from Zurich and Amsterdam to London ran studies of their own. Bremen ordered a feasibility study in 2019. In Schwerin, DHL and the local transit operator tried parcel trams, but dropped the service in 2024 after about a year, citing lack of demand and vandalism — a reminder that Dresden's version worked because one factory's steady parts flow justified the whole loop.
