Budapest's Century-Old Freight Trams Still Serve the City After 100 Years
With the distinctive toot of a horn, the ring of a bell, and the hiss of air brakes, an unusual rail vehicle emerges from a depot in Budapest. This vintage freight tram, known locally as a muki, continues to serve the Hungarian capital's public transit system, a role it has faithfully performed for an impressive 100 years.
The so-called freight trams operate on electricity from overhead wires and travel across Budapest's extensive tram rail network, which ranks among the busiest in the world. However, unlike the hundreds of iconic yellow passenger trams that carry commuters daily, these specialized vehicles have a different purpose entirely.
A Legacy Born from Necessity
Acquired by the city in 1926, the wood-sided trams were originally a product of post-war necessity. Following the destruction of much local freight infrastructure during World War I, they were designed to transport goods and raw materials to and from Budapest's factories.
"Engineers at the time created an electric drive system primarily using parts from vehicles damaged in the war, along with components from vehicles already designated for scrapping," explained Ádám Zadravecz, head of tram vehicle development and technology at Budapest's public transit company BKV.
He added, "Their primary purpose was freight transport, but after World War II, these vehicles were also utilized for the removal of war ruins."
Evolution of Function Over Decades
As Hungary recovered and modernized, the mukis' functions evolved significantly. During the 1960s, some of the original 40 trams were equipped with snowplows, enabling them to clear the city's tram tracks during winter months—a task they continue to perform today.
These versatile vehicles also conduct essential nighttime maintenance runs and transport broken-down trams into depots for necessary repairs. Over the decades, various parts have been gradually replaced, resulting in what maintenance crews describe as a practical mishmash of components.
By 2018, the aging fleet required a more comprehensive refurbishment. "When they were manufactured in the 1920s, they were extremely simple, extremely puritanical devices," noted Nándor Meixner, head of vehicle maintenance at Budapest's Ferencváros depot.
He continued, "During the refurbishment, we strove to make our colleagues' work easier. That is why, for example, a seat was added to the vehicle, so the driver can at least sit down." Another significant addition was the installation of heating in the driver's cabin.
Remarkable Durability and Simplicity
Despite these modifications over the past century, Zadravecz emphasized that the trams' fundamental nature remains unchanged. "Their maintenance costs are almost zero because these trams are very easy to maintain," he stated.
"Compared to the complex electronics of today's vehicles, there is very little in them that can break down. People say that they can be repaired with a hammer and a file, and that's absolutely true."
However, operating these historic vehicles requires specialized training and what Meixner described as a particular "feel" for the machinery. "It is not enough to just drive, to know the signs and instructions; you also need to know the vehicle itself," he explained.
Meixner elaborated, "We used to say that the driver has to drive this vehicle with his butt, meaning through instinct and experience rather than just technical knowledge."
A Diminished but Valued Fleet
Of the original fleet of 40 mukis, only six have survived the past century in Budapest, with just three remaining in active service today. Yet their value to the city's transit system remains significant.
"The value of these vehicles lies precisely in their simplicity, in the pure fact that they exist and are available to us," Zadravecz concluded, highlighting their enduring contribution to Budapest's transportation infrastructure.
These century-old workhorses continue to perform tasks that modern passenger trams cannot handle, from plowing snow to hauling broken-down vehicles, proving that sometimes the oldest solutions remain the most practical.
