The Ufa train disaster was a railway accident that occurred on 4 June 1989, in Iglinsky District, Bashkir ASSR, Russian SFSR, Soviet Union, when an explosion killed 575 people and injured 800 more.

In 1985, an excavator caused severe mechanical damage to the pipe in the form of a 1.7 metres (5.6 ft) crack during bypass construction.

[3] At 1:15 a.m., two passenger trains of the Kuybyshev Railway carrying approximately 1,300 vacationers to and from Novosibirsk and a resort in Adler on the Black Sea exploded, 11 kilometres (6.8 miles) from the town of Asha, Chelyabinsk Oblast.

[6] Many of the victims died later in hospital; official figures are 575 dead and over 800 injured,[2] but an unofficial estimate of the number of deaths is approximately 780.

[8][9] On the afternoon of 4 June, Mikhail Gorbachev, Chairman of the Supreme Soviet of the USSR, and members of the government commission to investigate the accident visited the site.

The charges were brought under Article 215, part II of the Criminal Code of the RSFSR, where the maximum penalty was five years imprisonment.
