(a) Light rain and dust accumulation on the insulators at Leighton, caused intermittent electrical faults which resulted in a loss of overhead power.
(b) The loss of overhead power resulted in Fremantle line train services being delayed which then cascaded onto Midland line train services.
(c) Generally speaking, weather conditions which impact timetabled services predominately occur in summer periods where heat wave conditions prevail. In the summer of 2008-2009 there 13 occasions when train speeds were reduced as a consequence of heat and five occasions in the summer of 2009-2010. The number of delays in the summer of 2009-2010 was reduced due to the cement resleepering program which is designed to improve track stability and create less impact on train speeds in heat wave conditions.
