Are you taking the piss? It's none of that.For all the good the metro line does, it sure has been out of service a lot since it opened. Why are they so unreliable? Is it poor equipment, poor design or both?
It has hardly been out of service since its inception unless it has been for transitioning for testing for the extensions of the line.
The first section Tallawong to Chatswood opened with a few teething problems in 2019. So be it, as it was new train technology in Oz. The small problems were corrected pretty quickly.
When the Chatswood - Sydenham extension opened (through the city), yes there was some closures required for testing for it. It had nothing to do with the reliability of the system.
With the lessons learnt from the stage one opening, the stage two actually worked really well.
Now that stage 3 is getting close to opening (Sydenham to Bankstown), line closures need to take place for that further testing. The regular closures have nothing to do with the reliability of the system.
Your claim that it is unreliable is wrong.
It actually is the most reliable rail line in Sydney, with a 99.5% on time service. It's automated of course, which pretty much ensures this.
