The Locomotive 293 derailment was a train accident that occurred on 16 April, 1917, near Finland Station, Petrograd, Russia. Most passengers miraculously survived, save a few scrapes and bruises, except Vladimir Lenin, who was mortally wounded. Lenin and several other passengers were thought to be involved with the revolutionary Bolshevik Party.
The incident was caused by a broken rail, which, according to some observers, was clearly tampered with and intentionally broken. Many attribute this to the work of Boris Yevdokimov, aka. Viktor Zharkov. Yevdokimov worked for the Russian secret police during World War I, and his alias was strongly trusted by Lenin and the other Bolsheviks.
