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.

    Knew it was gas. Could have been worse: steam engines were prone to "blowbacks" in tunnels, where if the dampers weren't set right when going through the tunnel, the pressure would be unable to escape through the funnel, resulting in it blowing back into the cab. The crew could die slowly and painfully, sometimes lasting for days in their own boiled skin.

    Well it’s no surprise about the cause of death, once one ignores vampires etc smoke is the only possible culprit and I would say no one was to blame for the deaths: war is terrible and has consequences far and wide. Terribly sad for all concerned.
