WELLINGTON
REGIONAL RAIL
STRATEGIC DIRECTION 2020




Where we’ve 
come from
Rail has been a key component of the Wellington Region’s transport network for more than 150 years. 
The first rail line was built in the 1870s between Wellington and Wairarapa. What is now known as the 
North Island Main Trunk followed in the 1880s, providing a more direct route to Manawatū and the north. 
Two branch lines were later added. 
The region has grown around the rail network, as villages have turned into towns and cities. Much 
of it was actively built around rail as transit-oriented development. Rail has become an increasingly 
important way for people to move about, particularly to Wellington’s CBD, and services and 
infrastructure have been continuously expanded and improved to serve an ever-growing population. The 
region is a leader in per capita use of public transport.

Rail capacity and service levels will need to increase to respond 
to the RLTP targets. To do this, the MSP anticipates that current 
initiatives will need to be completed, including proposed

Masterton and Palmerston North. The MSP supports detailed

The RLTP targets equate to 13.6 million peak passengers by 2030 
(compared to 9.7 million in mid-2019). This is considered a stretch 
target due to COVID-19 impacts and long lead times for infrastructure 
and rolling stock. However, the Let’s Get Wellington Moving (LGWM)

What we need 
to address
To make this a reality, the following improvements, and steps to get there are required to provide the 
needed capacity and make rail the preferred choice of travel:
Improvements

Improvements to peak and off-peak frequency 
Renew behind-the-scenes rail network

infrastructure to enable more frequent services
Improvements to rail capacity
Buy more trains to operate at higher

Improvements to overall access and station facilities to 
Station improvements that include easier access by a

Addressing these issues will enable us to achieve our vision of a rail system that 
provides safe, customer focused and efficient rail passenger and freight services, and 
supporting infrastructure, to drive the region’s economic development and social 
To support this, we propose the following investment pathway
