Closing rural railway lines will mean more trucks on roads

by Gareth Hughes

The crash between a logging truck and a school bus in Ruatoki yesterday was a tragedy. I am sure that, like me, you are hoping that the children involved will be able to make a full recovery.

The crash reminded me of what a transport advocate said some days ago when she came down to Wellington for our Smart Transport conference. She said, “I’ve been driving around Wellington for a few days now and I knew there was something different about the city. Then it suddenly struck me – there are no logging trucks here.”

She went on to talk about how the community in Whangarei fears that one of the impacts of closing the Northland to Auckland rail line will be more big trucks on their roads.

They say the Whangarei rail line carries 12,000 tonnes of freight a year – which means they will have about 200 extra trucks per day on their roads if the line closes.

As we highlighted in 2009, when the Minister was considering whether to allow bigger trucks onto our roads, trucks are disproportionately likely to be involved in fatal accidents.

According to the Ministry of Transport trucks are involved in 16% of fatal accidents on the road although they are responsible for only 7% of vehicle kilometers travelled.

Sadly, however, the Minister subsequently approved a law change to allow even larger juggernaut trucks onto our roads. Since then Kiwirail has also started consultation on whether to close some of our rural railway lines.

I’ve been involved with community groups that have campaigned to keep the Northland to Auckland and the Gisborne to Napier railway lines open.

Over the last year both groups have collected thousands of signatures on petitions to save the lines and organized many community events. The passion they have shown to keep these lines open is astonishing.

I can only hope that the government will heed their calls and require Kiwirail to look seriously into finding more customers to make these lines viable.

In some areas it may be that to keep the lines open we need to invest more into maintenance or even extend the line. For example, in Northland it would probably help the line to remain viable if it was extended out to Marsden B Point, one of New Zealand’s best ports. These maintenance projects are often expensive but their cost pales in comparison to the billions our government is borrowing and pouring into uneconomic and unnecessary motorways.

I believe there are many compelling reasons to keep our rural railway lines open. These include giving us another, more fuel-efficient option for transporting freight if the price of fuel raises sharply, to prevent climate change through reducing our greenhouse gas emissions, and to give these regions economic development options.

But when considering whether or not to keep the lines open Kiwirail should also not forget to take into consideration the fact that every tonne of freight carried by rail is a tonne off our roads – which means a safer environment for all those travelling in rural areas.

UPDATE: Various people have questioned the figures on rail freight I provided in this blog. You were correct, I’m afraid I repeated the numbers somebody else had mentioned to me without doing my own background research. In fact, according to this report, the Northland to Auckland rail line carried 300,000 tonnes of freight/year in 2006 (a drop of 700,000 tonnes/year since there ceased to be a direct link between the rail line and the port back in 2000).

At an average weight per heavy vehicle of 6.9 tonnes that equates to a further 836 heavy vehicles/week on Northland’s roads if the rail line closed. If you assume that all the weight would be carried by very large trucks (with an average weight of, for example, 30 tonnes) then that equates to 200 additional trucks/week.
