2005 Deelfontein train collision
From Wikipedia, the free encyclopedia
The Deelfontein rail crash was a collision between two trains including the prestigious Blue Train at a crossing loop in South Africa in October 2005.
The cause of the accident was found to be a wrong side failure in the signalling, caused by solder splatter in one of the interlocking relays. [1]
[edit] Aftermath
The signalling circuit improperly bridged by the solder splatter appears to have been single-switched. To prevent a recurrance, double switched circuits are proposed, also called secondary protection circuits.
