Get on track to a greener and more comfortable tomorrow
Rail is among the most energy efficient modes of transport, but increased requirements have made trains heavier and more expensive to operate. With Armacell’s solutions, you can take your rail projects BEYOND BETTER by improving energy and cost efficiency without compromising passenger safety and comfort.
Maintaining rail’s position as the green choice
Today, rail is among the most energy efficient modes of transport. Carrying 8% of the world’s passenger and 7% of global freight transport, it represents only 2% of total transport energy demand. Governments and cities encourage the uptake of public transport as a means of decarbonising cities, reducing air pollution and improving land use management. But with increased demands, the rail industry is continuously looking for ways to enhance energy efficiency, sustainability and durability.
Lightweighting holds the key to increased sustainability and durability
Investment in rail infrastructure is expensive and extensive. But as the world transitions towards a more sustainable future, there is an opportunity for rail developers and operators to support increased rail usage. This requires innovation to enhance operational efficiency and better customer experience. Lightweighting offers the benefit of lower energy requirement and in turn reduced fuel costs and carbon emissions. Lower mass and consequently lower axle load also offers lesser track damage and potential for a “virtual spiral” of positive synergies where reduced mass results in reduced forces, reduced strength requirement and further mass reduction.
What influences the efficiency of trains
The high energy use of auxiliary systems
Auxiliary systems of trains, most prominently HVAC systems, account for up to 20% of a passenger train’s total energy consumption.
The body accounts for 25% of the weight
In a typical passenger-design railcar, the railcar body itself accounts for approximately 25% of the total weight.
How to reduce weight
Railcar weight can be reduced by around 15-20% by using multi-materials and optimisation techniques.
