MaRTI proposal impacts public transport development

Chat Club (Christchurch Housing And Transport) has today released its proposal for Kiwirail to relocate its Middleton rail yards to the Rolleston area to enable the existing site to be freed up for affordable housing development.

Currently as many know, Middleton is the historical site of the main Kiwirail freight handling yards for Christchurch. It is also closely connected with local rail served transport logistics hubs operated by several of New Zealand’s major freight companies, such as Mainfreight, Daily Freightways and PBT, although their sites are to the west of the freight yards, closer to Sockburn, and may not be directly affected if the proposed area of redevelopment is strictly confined to the current Middleton site.

Middleton was first developed for rail freight around 100 years ago and an early development there was for the purposes of creating a hump shunting yard, similar to the one that was developed at Te Rapa near Hamilton in the North Island. The Middleton hump facilities, like the ones at Te Rapa, were removed later on. Middleton was just one of a number of freight facilities in Christchurch until the mid 1980s when work began on rationalising yards due to the increased competition from road transport at that time. It then became the major shunting yards for the whole city and relocation of various ancillary functions from other parts of the city, such as the locomotive running depot from Linwood, have continued to the present day.

At the present time Middleton forms the nucleus of the bulk of rail operations in Christchurch, with most freight and support operations handled either at the yard itself or at Sockburn to the west and Addington to the east. Woolston and Lyttelton also handle freight further east, both mainly used by Port of Lyttelton, whilst logs are the main traffic now handled at Hornby.

At the present time the main running lines from Lyttelton to Middleton are double track. From Middleton to Sockburn there are four main lines due to the volume of freight handled on private sidings in the area. The Third Road ends at the Sockburn overbridge while the Fourth Road to Hornby where it connects to the Hornby Industrial Line. We could expect to see these lines remain in their current form. From Sockburn to Islington is double track. The line was singled between Islington and Rolleston in the 1990s. We could expect to see this line doubled again if the railfreight yards were relocated to Rolleston as suggested in the proposal. The main lines at Middleton itself were diverted around the southern side of the rail yard some years ago and probably would not need to be relocated.

The main questions related to this proposal include the following:

  • Impact on freight handling from Middleton yard into the rest of Christchurch.
  • Impact on rail operations, including the relocation of the locomotive depot.

Both of these issues can be handled to some extent using other rail properties in the city. Land may be available at Linwood, unless it has been sold.

The proposal densifies the rail corridor between Christchurch and Rolleston, and will be potentially beneficial to proposals for commuter rail for Rolleston, although there are a number of obstacles to be overcome to make this traffic viable.

We are currently preparing historical maps for Middleton for the NZ Rail Maps project which will be posted in the next day or two either on this blog or NZ Rail Maps.
