Sydney light rail extension to open soon

Light rail services between central Sydney and Dulwich Hill in the inner west will begin next week, with services running every 10 minutes during peak times.

Work on the $176 million track extension finished last month but about 250 hours of safety testing was needed before the project could be given the go ahead.

"Come March 27, next Thursday, customers will be able to go all the way from central to Dulwich Hill on the new inner west light rail extension," NSW transport minister Gladys Berejiklian said.

Journeys from the city to Dulwich Hill on the extension will take about 40 minutes.

But Ms Berejiklian said the benefit of the light rail service was its regular departures.

"In the peak, passengers can expect a turn-up-and-go service every 10 minutes and in the off-peak they'll get a regular 15 minutes service," she said.
