To make the most of infrastructure investments, the playing field for rail freight needs to be evened out, writes Caroline Wilkie, CEO of the ARA.
The confirmation of funding for the Port of Melbourne direct rail line to South Dandenong in August was welcome news for business, industry, and residents in the region.
The direct rail connection to the port forms part of the wider Port Rail Shuttle Network and will make it easier and more cost effective for businesses to access port facilities.
The Federal and Victorian government funding will deliver tangible benefits to businesses in Dandenong’s manufacturing sector and improve the efficiency of port operations.
Ultimately, the project will also take 100,000 trucks off the road, helping give local residents their city back in the process.
In the same month, the NSW government fast tracked approvals for the Botany Rail Duplication and the Cabramatta Rail Loop, putting its support behind greater use of rail within its freight network.
The projects will not only deliver this critical new infrastructure to meet the state’s freight needs but will take 54 trucks off busy city roads with every additional freight train travelling on the Botany line.
That will make a crucial difference as the Port of Botany’s freight task increases by 77 per cent in the 20 years to 2036.
As Minister for Regional Transport and Roads Paul Toole observed when announcing the approvals, these new connections are so important because the more freight is moved on rail, the less congestion there is with fewer trucks on the roads.
These projects are great examples of the difference rail freight can make, and why continued investment is essential to the continued liveability of our cities and towns.
But while the benefits of projects like these are obvious, more needs to be done to ensure the rail sector can meet our increasing freight needs.
While Australia’s freight task is growing – and will continue to grow – the role rail freight plays in meeting this demand has actually declined.
Recent years have seen the rail industry’s share of the freight task eroded by policy settings that favour other modes of transport and frustrate investment in the sector.
As a result, less than one per cent of freight travelling between Sydney and Melbourne is moved by rail – a far cry from the 40 per cent share the rail network maintained in the 1970s.
While the vast expanses of the country have seen east- west connections hold up better, rail freight’s modal share has started to slip there too, with rail now carrying just 54 per cent of the freight task across the Nullarbor.
It is hard to reconcile the declining role of rail freight at a time where the sector needs more capacity than ever before.
Part of the problem is how we price rail freight when compared to road.
While getting trucks off the roads remains a focus in these busy and often congested urban areas, heavy vehicle road reform has simply not progressed.
So, while rail freight access charges are based on maintaining and operating the infrastructure it requires, the road freight industry is not expected to fully cover the cost of maintaining and operating the roads it uses.
As we hear more about the importance of easing congestion, the sustainability benefits of using more rail services and the value of creating city precincts that make it easier for residents to get around, favourable pricing models for road freight is increasingly difficult to reconcile.
We must have a level playing field for all to ensure rail freight can grow to support the increasing demand for freight across the country.
This, together with harmonisation of standards across the country, could enliven the rail freight sector again and ensure it is ready to support the growth of our economy over time.
After all, the industry has shown how much can be achieved under the right settings.
Australia was the first country to move to fully autonomous freight trains when the mining sector adopted the technology to service iron ore mines in the Pilbara.
This capability has become a hallmark of mining in the region and the significant benefits the industry delivers to the broader economy.
Use of rail for bulk commodities has increased, bucking the trend of the broader sector.
With a level playing field and certainty of standards across the country, there is no telling what additional benefits further innovation in the sector could deliver.
But first, we need to get the basics right so that rail freight can compete equally and fairly.
After all, we cannot allow new investment in rail infrastructure that busts road congestion in our cities to be eroded by a policy environment that only encourages business and industry back to the roads in the end.
Aurizon will invest $50m in low carbon locomotives such as battery and hydrogen-powered trains to meet a net zero goal by 2050.
The freight hauler and network owner will also look to maximise the benefits of the electrified freight network in Queensland, particularly as more renewable energy is fed into the grid.
Managing director and CEO of Aurizon, Andrew Harding said that the company was confident that technology would meet the company’s goals.
“We are confident that rapidly-advancing technology in the rail sector will unlock major benefits like we are seeing in motor vehicles, energy generation and general industry. Our focus will be low-carbon technology for our locomotive fleet which accounts for more than 90 per cent of Aurizon’s CO2 emissions.”
In addition to actions undertaken internally, Aurizon will also push for government action.
“We directly advocate for policy actions to increase the use of rail freight on key national freight corridors. Our aim is to ensure that rail freight remains competitive and part of the solution as the economy transitions to a low-carbon future,” said Harding.
The company’s commitment follows the latest Sustainability Report from the freight operator. In the report, Aurizon advocates for lowered electricity costs to reduce the risk of substituting electric locomotives for diesel-powered trains. In addition, Aurizon outlines that the company has been advocating for greater infrastructure investment, improvements to regulation and finding efficiencies at interfaces between modes.
To meet the goal of lower emissions, Aurizon said that it would be making significant investments in new rollingstock shortly.
“Aurizon is already working with other railroads and manufacturers on the early development of battery and hydrogen-powered locomotives for deployment in a heavy-haul railway environment. This includes options of upgrades to the existing fleet and new rollingstock. We would expect to see prototypes trialling on our network by 2025, as technology advances and costs come down further,” said Harding.
“Locomotives are long-life assets of 20 – 30 years. We have some significant decisions ahead in renewing our locomotive fleet – potential game-changers for the freight industry – when we invest in the next generations of rollingstock to power our business through to 2050.”
Construction will begin next year on two level crossing removals in Glen Huntly.
The level crossings at Neerim and Glen Huntly roads will be gone by 2023 and the project completed by 2024, a year ahead of schedule.
The crossings will be replaced by lowering the Frankston Line into a trench, and constructing new road bridges for both crossings.
Removing these level crossings will only benefit the 20,000 vehicles that travel through the two level crossings a day, but also improve journeys for tram passengers on route 67, which crosses the rail line at Glen Huntly Road. The crossing at Glen Huntly Road is one of Melbourne’s last tram squares, a manually operated crossing used by trains and trams, which slows trains down significantly.
200 trains pass through the crossings each day, causing the boom gates to be down for half the morning peak.
In addition to the level crossing removals, the new Glen Huntly station will be part of a new precinct, increasing connectivity and improving community safety, said Victorian Minister for Transport Infrastructure Jacinta Allan.
“Our level crossing removal project isn’t just getting rid of those dangerous and congested boom gates – we’re delivering new train stations, more open space and new pedestrian and cycling infrastructure.”
The two crossings in Glen Huntly are the last to go on the Frankston Line, and when complete, the 18 crossings between Flinders Street and Moorabbin will be gone.
A number of new stations have had their designs revealed, with Bell and Preston stations being upgraded with colourful designs that reference the local communities.
For North Williamstown station, a priority was maintaining the village feel of the local area. Improvements to lighting, landscaping and crossings, will improve local connectivity and safety.
The new Glenroy Station, which is part of the level crossing removal at Glenroy Road, two sides of the rail line will be reconnected for the first time in 100 years.
“We’ve removed half of the 75 level crossings we promised, well ahead of schedule – and with works continuing in line with strict safety protocol during the pandemic, we’re not wasting a minute getting the rest gone for good,” said Allan.
In the same way that the inflexible old oak trees get uprooted in a strong storm in Aesop’s fable, a track support with too high track stiffness will cause premature failure and result in higher maintenance costs than anticipated. Track support that is too stiff does not spread the load sufficiently, resulting in extremely high localised impact loads and stresses (in track, sleepers, and fasteners). This may result in microcracks in rigid sleepers, failure of screws or clips, ballast attrition or ground vibrations. Causes for too high track stiffness include rigid subgrade (including concrete bases such as bridges, viaducts, tunnels) and overly stiff sleepers, such as concrete sleepers. Read more
Hydrogen trains have met all four test requirements in a trial conducted in the Dutch province of Groningen.
Local operator Arriva trialled Alstom’s Coradia iLint trains, in partnership with railway infrastructure manager ProRail and energy company Engie over two weeks in March, 2020. The trains were tested on the line between Groningen and Leeuwarden.
The trial had four objectives for the hydrogen-powered trains: authorisation by the Dutch national safety assessor to run on the Dutch railway network; zero emissions in the commercial service of the current timetable; quick and easy refuelling; and familiarising the general public with hydrogen mobility.
On all four objectives, the trains met the requirements.
“The tests have demonstrated how our hydrogen train is mature in terms of availability and reliability, providing the same performance as diesel equipment, and with the benefit of low noise and zero emissions. The Coradia iLint hydrogen train supports the transition towards global sustainable transport systems,” said Bernard Belvaux, managing director, Alstom Benelux.
To meet the commercial service performance requirement, the trains were tested on an all stations service and an express timetable. The trains were tested on fuel consumption, compatibility with infrastructure, acceleration, braking, docking, and maximum speed. All went without a hitch.
During the trials, the trains were found to be significantly quieter than current diesel trains. Drivers were also familiarised with the trains and found them smooth, comfortable, and easy to drive.
Powered by hydrogen produced from renewable energy, refuelling went faster than expected and was conducted safely.
The Netherlands follows Germany in testing Alstom’s hydrogen-powered trainsets.
“After Germany, the Netherlands is the second country in Europe where the Alstom’s hydrogen train has proven itself a unique emissions-free solution for non-electrified lines,” said Belvaux.
Other trails and plans for implementation are being developed in Austria, Italy, and the UK.
