VLOCITY train services between Traralgon and Melbourne will resume with a new timetable from March 21, with all but two services returning as trains.
Diesel trains running from Sale continue to be unaffected.
Public Transport Minister Jacinta Allan, announced on Tuesday work to reduce wheel wear, accelerate maintenance and fix boom-gate detection issues had been more effective than anticipated.
Travel will continue to be free on the services still running as coaches, the 11.20am and 16.15pm services from Traralgon.
Installation of track detection devices on metropolitan level crossings used by regional trains remains on track for completion by March 11, which will allow current restrictions on VLocity trains on the Gippsland corridor to be lifted. Eastern Victoria MLC Harriet Shing said 95 per cent of Gippsland services would soon operate as trains, returning almost 2500 passengers to rail services.
She said 26 services were currently running as coaches on the Gippsland line, but in two weeks there would be just two, and by the middle of the year all services should be back on track.
