Sydney's inner-west light rail resumes

The line was closed in November after cracks were discovered in the wheel arches of all 12 tram sets.

NSW Transport Minister David Elliott says from February 12 six trams from the eastern suburbs light rail sector will begin operating on the inner-west line at 15 minute intervals.

"Services will operate between Dulwich Hill and Central Station, which is the full line," Mr Elliott said on Sunday.

"This is better than the original plan to run these returning services between Lilyfield and Central while the inner-west trams are being fixed."

Mr Elliott said repair work on the network's fleet was under way, with all 12 trams "on track" to be fixed by the end of 2022.

Transport for NSW chief operations officer Howard Collins says the station platforms, track and speed limits have all been changed on the inner-west line.

"Staff will be on hand to provide customer service on the ground as and when required," Mr Collins said.

Opposition transport spokeswoman Jo Haylen said passengers will welcome the return of some services on the line after going without them for more than 100 days.

"Make no mistake, the government has cobbled together a bandaid solution to a transport disaster completely of their making," Ms Haylen told reporters on Sunday.

"Twelve overseas-made trams cracked and out of service and the government is no clearer on what the engineering solution is."

Ms Haylen warns the "transport saga" is not over.

"Those trams still have to be fixed and the government is yet to admit its fundamental mistakes here," she said.

"It is yet to admit that the failure to integrate the inner-west light rail line with the eastern suburbs light rail line is a massive mistake but most importantly that buying off-the-shelf overseas models of trams, ferries and trains is a complete failure."
