Looks to be years to go until Wairarapa trains are back-on-track. 

Only 22.5% of Wairarapa trains arrived within five minutes of being on schedule in April. slightly improving from February's 5%. 

Trains have also been slowed due to track issues. 

Greater Wellington Regional Council Transport Committee Chair Thomas Nash told Mike Hosking that both the track and trains are too old, but work is ongoing. 

He says we need to make sure we don't delay the new trains even further.
