Aerowagon

The Aerowagon or Aeromotowagon () was an experimental high-speed railcar fitted with an aircraft engine and propeller traction invented by Valerian Abakovsky, a Soviet engineer from Latvia. It produced speeds of up to . The Aerowagon was originally intended for the express transportation of important documents and to carry Soviet officials on government business.

Crash incident

On 24 July 1921, a group of delegates to the First Congress of the Profintern,The Communist International, organ of the Executive Committee of the Communist International, no.19, led by Fyodor Sergeyev, took the Aerowagon from Moscow to the Tula collieries to meet with local miners and to visit an arms factory. Abakovsky was also on board. Although they successfully arrived in Tula, on the return route to Moscow the Aerowagon derailed at high speed near Serpukhov, killing six of the 22 people on board. A seventh man (Paul Freeman) later died of his injuries.Letters from Tom Mann to Elsie Mann, Moscow, 26 and 30 July 1921; archives of Tom Mann, Modern Records Centre, University of Warwick, document references: MSS.334/3/6/5-6.

An official investigation concluded that the cause of the derailment was the poor condition of the railway track. Artyom Sergeyev (the son of victim Fyodor Sergeyev and also the adopted son of Joseph Stalin) claimed sabotage arranged by Trotsky.

Deaths The following people died as a result of the accident: , Bulgarian delegate Paul Freeman, Australian delegate , German delegate William James Hewlett, British delegate Fyodor Sergeyev (known as "Comrade Artyom") , German delegate Valerian Abakovsky, the Aerowagon's inventor

All seven men lay in state at the House of the Unions, after which they were buried with honors in the Kremlin Wall Necropolis. Sergeyev is buried in Mass Grave No. 12, Konstantinov, Abakovsky and Freeman are buried in Mass Grave No. 13, while Strupat, Helbrich and Hewlett are buried in Mass Grave No. 14.

Legacy

The Aerowagon was a precursor to the German Schienenzeppelin railcar, the American M-497 Black Beetle railcar and the Soviet turbojet train, all three of them being experimental vehicles featuring the combination of railcar and aircraft engines.
