V/Line execs in front of Vic committee

The chief executive of Victoria's troubled regional train service V/Line will appear before a parliamentary committee on Tuesday.

The chief executives of Public Transport Victoria and Metro Trains will also appear before the committee at midday.

V/Line has had to cancel hundreds of services since January 16 over maintenance problems with wheels and an issue with boom gates not triggering properly.

The last time executives appeared before the committee they revealed that the government was spending up to $300,000 a day to hire replacement buses for cancelled services.
