Deelfontein rail crash

Encyclopedia : D : DE : DEE : Deelfontein rail crash

In the Deelfontein rash crash two trains including the prestige Blue Train collided at a crossing loop. This occurred 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. RailwaysAfica Issue 1/2006

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.
