Trains were disrupted by lightning strikes on the Blue Mountains line on Tuesday.
Electric train services stopped just after 8.30am on Tuesday after a loss of power supply from the area’s network.
A spokesperson for NSW TrainLink said the outage had been caused by lightning strikes.
“There were also impacts on rail infrastructure including a lightning strike on a high voltage overhead power line and trees down on signalling equipment,” the spokesperson said.
Buses replaced train services between Katoomba and Lithgow while repairs were carried out and power was restored to the network.
Normal train services resumed on Wednesday morning. NSW TrainLink apologised to its customers for the disruption.
The weather continues wet across the region. While Lithgow dodged the serious thunderstorms, the Bureau of Meteorology recorded about 12mm of rain on Wednesday.
