Deadliest railway accident in Italian history, in 1944

The Balvano train disaster was the deadliest railway accident in Italian history and one of the worst railway disasters ever. It occurred on the night between 2–3 March 1944 in Balvano, Basilicata. Over 500 people in a steam hauled, coal burning freight train (mostly stowaways) died of carbon monoxide poisoning during a protracted stall in a tunnel.

In 1943, Axis Italy was invaded by British and American armed forces, and the southern part of the peninsula (almost fully conquered by Allied forces) suffered severe wartime shortages, encouraging an extensive black market. People in large cities such as Naples began bartering fresh produce for commodities brought by servicemen, and stowed away on freight trains to reach their suppliers' farms. The railway companies also suffered shortages of good quality coal. The burning of low grade substitutes in locomotives reduced their power output and produced a large volume of carbon monoxide, an odorless and poisonous gas, a particularly severe problem in Italy's railway network, which crosses mostly mountainous land, and hence makes large use of tunnels with steep inclines of up to 3.5%. In February 1944, similar conditions resulted in one death on the Battipaglia–Metaponto railway when a man was poisoned by poor quality coal exhaust. He fainted, was crushed between the engine and the tender, and died. No corrective action was taken to prevent recurrences.

In the evening of 2 March 1944 the freight train 8017 started from Naples heading to Potenza. It consisted of 47 freight wagons and had a remarkable mass of 520 tonnes; it also carried many illegal passengers. The first part of the journey took place on flat railway, and the train was pulled by an E.626 electric engine. At 19:00 the train left Battipaglia and entered the steeper, non electrified Battipaglia–Metaponto railway; the electric engine had been replaced by two steam engines (the 480.016 followed by the 476.058). In Eboli some stowaways were forced off, but more boarded on following stops until they numbered about 600, making the train grossly overloaded. At midnight, the train arrived in the Balvano Ricigliano station, making it the last before the disaster, where it stopped for maintenance on the engines. At 00:50 the train restarted towards the adjoining Bella Muro station, and reached a speed of about
The station masters of Balvano and Bella Muro were blamed because they did not act to determine the location of the train when it appeared late on the roadmap. However, in the wartime confusion it was usual for communications to be irregular, and trains could be greatly delayed. It was not uncommon that it would take over two hours to travel the mountainous 7 km between the two stations. The staff of the train and of the stations along the route were also blamed, because they allowed such a heavy train to continue even if they knew that its engines were not powerful enough. However the provisions for the train came straight from the Allied Command, so railway workers could not stop the train and change its composition. The Command itself organized a train to check the condition of the disaster, with staff equipped with oxygen masks, which recognized the actual development of abnormal amounts of toxic gases. Ferrovie dello Stato Italiane declined all responsibility, claiming that in the complex end of war set up (where Italian authorities coexisted with the US command) they could not even immediately determine who had the responsibility for the management of one particular train. However the company could be blamed because at that time, despite the high demand on the route between Naples and Potenza, there was only one scheduled passenger train (train 8021), which left from Naples twice a week, on Wednesdays and Saturdays, which prompted an increase in illegal ridership on freight trains. In attempt to prevent criticism, the Ministry of Treasury issued to the families of all identified victims the same compensation which was given for war victims (although it was paid more than 15 years afterwards).

After the disaster, a limit of 350 tonnes was introduced on the entire line. In addition, for particularly heavy trains requiring two locomotives, a composition of an American diesel locomotive and an Italian steam locomotive was used in place of a double steam drive. Furthermore, at the south exit of the Armi tunnel a permanent guard post was established, which allowed trains to enter the gallery only when exhaust gases from previous trains had cleared. The guard post remained in place until 1959, when all steam trains were banned from the line. The weight regulations were repealed in 1996, when the line was electrified.
