About The Hutt Valley Line is the electrified train service operated by Transdev Wellington on behalf of Metlink on the section of the Wairarapa Line railway between Wellington and Upper Hutt, New Zealand. The route length is 32.4 km (20.1 mi). I believe this should be set in around 2011 to allow for the 3 types of trains to be operational.
