GROOVED BLOCK RAILS SHOW EXCELLENT BENDING CAPABILITIES EVEN DOWN TO RADIUS 20-25M.
Our grooved block rails are manufactured following the EN14811 standard, meeting the same quality standards as conventional grooved rails. Grooved block rails have considerable advantages over conventional grooved rails:
- No rail web (the vertical part linking the head and the foot of a rail): 50% less height. Only 70 mm in height, which considerably reduces construction costs.
- Less weight: 5-10% lighter.
- Reduced noise: 5-10 dB less (due to not having rail web)
When it comes to performance, grooved block rails show excellent bending capabilities even down to Radius 20-25m. In addition, tests have shown improved stress capabilities for tram and even heavy rail networks when compared to conventional grooved rails.
ArcelorMittal Europe-Long Products produces two grooved block rail profiles: 53K2 (MSzTS52), and 57K2 (LK1). The main difference is the wider grooved width in the case of 53K2 (MSzTS52) with 45mm. Our grooved block rails have been installed in a variety of countries including: Germany, France, Italy, Hungary, Poland, Czech Republic, Russia, Belarus, and in the United States (New York City, Washington, Portland, Dallas and Pennsylvania).
To complete the tram lines 49, 56, 61 and extend line 17 of Budapest tramway, ArcelorMittal is supplying over 1,000 tonnes of grooved block rails produced in Rodange. Onsite deliveries have already started and will continue up to the completion in 2018.
