On the rainy night of March 2nd, 1944, the overnight steam-power freight train 8017 from Battipaglia to Potenza, did not pass through the railway station at Balvano in southern Italy.
The station master there was not overly worried.
But later at 5:10 that morning, when one of the crewmen from the freight train staggered into the railway station, the Station Master knew something was seriously wrong.

    • Of all the places they broke down just happened to be in the tunnel with engines blocking both ends.... yeah... they say this was an 'accident' but makes you wonder if it was mass murder. Wedding rings, gold teeth, watches, shoes, cloths, cash. ... lots of motives.

  • Inside the tunnel was the presence of carbon monoxide, extraordinarily poisonous, it produced the asphyxiation of stowaways.

  • There was a similar accident in the alps in the 70's i think. A diesel train caught fire in a tunnel going up to a peak taking mostly skiers. People died of smoke as they were running upwards toward the end of the tunnel, not realizing the tunnel worked as a chimney, the smoke going up as well. Only those survived who chose to run down towards the bottom of the mountain.

    Maryann AilesMaryann Ailes10 päivää sitten
  • My guess is a tunnel fire, where its too far to the exits so people don't make it and die of smoke inhalation. I've heard of enough tunnel fires that I know that they are the most dangerous fires...

  • Well, the victims of the Balvano train disaster (Disastro di Balvano) is still disputed, I've seen some official sources say 517, others say 521, recent ones say more than 600. Just imagine how many died, even the survivors were disabled for life.

    Kevin KosasihKevin Kosasih27 päivää sitten
    • I've seen the Disasters of the Century version: The Black Market Express. One of the survivors survived because he had his scarf on his mouth and nose, which act as a filter that saved his life, but his hair turned grey as a result of the poisoning. Another survived because he slept inside a thick military cloth, which also acted as a filter. Another survived, but suffered heavy brain damage and lost his wife and son. A nearby chapel, built by a relative of two of the victims, now commemorate the disaster.

      Kevin KosasihKevin Kosasih27 päivää sitten
    • The video's also not accurate, the train was almost entirely stuck inside, not outside the tunnel, with only two carriages outside. There are 3 crew members inside each locomotive, all except one were killed by the fumes. There are two brake men, one killed by the fumes and the other managed to tell the news of the Disaster

      Kevin KosasihKevin Kosasih27 päivää sitten
    • Also the train's not full freight, it is a mixed train and double-headed due to the weight, the engines were FS Class 480 and FS Class 476. Both are steam engines
