Major Railway Infrastructure Projects That'll Impact the Corrosion Control Market
Major railway infrastructure projects are driving increased demand for anticorrosion and decorative coatings and corrosion monitoring services.
Transportation is a pivotal sector of the global economy because it fulfills some basic needs of human civilization. The global investments in infrastructure such as railways, roads and airports tend to increase the demand for decorative and corrosion-resistant coatings, corrosion monitoring services and related equipment. On the other hand, projects that are delayed or differred tend to reduce this demand.
Rising Demand for Rail Transportation Systems
Because of growing urbanization and peoples’ desire for faster mass transportation systems, there is increased demand for high-speed rail and metro rail systems in both the developed world and the emerging economies. Rising income levels in emerging economies, and the Asia-Pacific region in particular, are driving demand for high-speed commuting. Europe, North America and the Middle East regions also have rail infrastructure projects on the books due to a steady growth in demand.
China alone invested USD $570 billion in 2019 for rail infrastructure, while it continues ongoing projects for a huge rail network. There are plans to run 5,000 trains per year between European countries and China.
In this article we discuss some major railway infrastructure projects and the implications for the corrosion control industry.
1. Sydney Metro – Western Sydney Airport Project, Australia
Being built at a cost of USD $8 billion, the new metro rail project will service Greater Western Sydney and the new Western Sydney International (Nancy-Bird Walton) airport. The 23 kilometer metro rail project is scheduled to start in 2020 and be completed in 2026 with six metro rail stations. It is expected to create jobs and inject money into the NSW and Australian economy.
2. High Speed Rail of California
This California high speed rail (HSR) project that began in 2015 will connect San Francisco airport (SFO) to San Diego. It will be a renewable energy based project implemented in two phases.

8. Texas Central Rail (Dallas – Houston) Project
Construction is scheduled to begin in late 2020 for a USD $20 billion rail line between Houston and Dallas that may take six years to complete. This will be the first privately owned and funded high-speed railway project in the world. Once the project is completed, the high-speed trains between Houston and Dallas will cover the 390 km distance in 90 minutes. Texas Central, the company promoting the project, has awarded the construction contract to Salini Impregilo, an Italian construction company.
9. Calgary Green Line Light-Rail Train (LRT)
This Canadian project involves adding 46 km of track with 28 rail stations to an existing 59 km light rail network. Construction work will continue from 2020 through 2026. The project includes important infrastructure construction in the Centre City Tunnel in the initial phase. It is expected that 41 million passengers will travel in this train per year.
10. Las Vegas – Victorville 270 km Rail Line
This USD $8 billion high-speed railway project is intended to connect Las Vegas and Victor Valley. The project is being funded through a USD $3.2 billion bond package from California Infrastructure & Economic Bank. Construction is likely to commence in 2020 and completion is planned for 2023. Extension of this line to Los Angeles is also being considered.

It is estimated to cost 58 billion Yuan (approximately USD $8.35 billion) and will take 54 months to complete. The route will have 7 rail stations. This is part of 3,200 km of high-speed train networks planned in China, at an investment of USD $125 billion. The increase in rail and other infrastructure projects is unfortunately coinciding with an economic slowdown as well as the Covid-19 pandemic; therefore the additional funding works as a stimulus package for economic recovery.
Impact of Railway Infrastructure Projects on the Coatings Market
Today's railway coatings are required to improve the train's ambiance with bright colors and smooth textures for passenger comfort as well as provide anti-corrosive performance to the rail systems.
The rail coatings demand is likely to grow as the Asia-Pacific region (Japan, Taiwan, South Korea, China) dominate new railway infrastructure investments. Demand for rail coatings is expected to grow at a compound annual growth rate (CAGR) of 4.5 percent.
According to one study, acrylic resin-based coatings (both solvent-based and waterborne dispersion forms) that are extensively used on internal and external metallic surfaces in locomotives and rail coaches will dominate the market. (The advantages of waterborne coatings are examined in Waterborne Coatings: Environmental and Health Regulations Meet Coatings Technology.)
The advantages of acrylic products include their resistance to UV radiation and glossy appearance, color retention and good adhesion to metals. Acrylic coatings are selected for use on internal and external surfaces of locomotives, passenger rail cars, wagons and rail parts.
Innovative and proprietary zinc-based rail coating products are being developed and offered by manufacturers to meet the stringent requirements of coated rails, especially for operations in aggressive surroundings such as coastal environments with moist and salty conditions and in the Middle East, where salty sand can come into contact with the rails. In addition to fertilizer factories and other infrastructure projects, railways will be a key driver of zinc demand in India.
Galvanized rail tracks can improve rail safety as well as maximize the track's service life. In India, rails, fish-plates and bolts need corrosion protection, particularly in coastal regions where 125,000 km of rail lines experience losses of USD $628 million (4400 million rupees) annually due to early replacement costs.
Impact of Railway Infrastructure Projects on Corrosion Monitoring and Control Services
Railway infrastructure is one of the drivers of growth in the corrosion control market because rail base corrosion and stray current corrosion are some of the major causes of rail system breakdowns. As a result, there will be increasing demand for regular inspection and corrosion monitoring and control services. (New infrastructure projects try to prevent corrosion in the first place. Read How to Control Corrosion by Improving Design for more information.)
The corrosion monitoring system market is growing at a CAGR of 7.8%, from USD $242.4 million to a projected $410.3 million in 2027. This demand is due to maintenance requirements and assets bought for new projects.
Demand for new railroad infrastructure is increasing due to a growth in urbanization and the passengers' desire to reduce travel time. Recently initiated and new construction projects will impact thousands of kilometers of rail infrastructure development. As a result, the railroad coatings market is expected to grow at a compound annual growth rate (CAGR) of 4.5% until at least 2025. Similar increases in demand for corrosion monitoring and corrosion control services are also expected.
