Ballastless Track for Urban Metro
Patil group is the pioneer in bringing Ballast-less tracks for the metro. These systems have been designed and engineered by Patil group in collaboration with our in-house Research and development teams and collaboration with global partners. Urban metro requires very high availability of the track. Only ballast-less track can provide this availability ensuring least maintenance and high strength. Following metros are already using such type of plinths in India.
Apart from the above cities, Pune Urban Metro Rail is also planning to use Pre-cast plinth, which is a very innovative design done by Patil group.
1.Pre-cast plinth:
The Pre-cast plinth Type Ballastless Track is a well proven design used at 3 metro train projects across the world. This design has been developed by Patil Group in co-ordination with leading international design consultants. The pre-cast plinth track system is a continuously supported rail with discrete shoulders retained by rail clips.
Pre-cast plinth system of Urban Metro is meant for speeds up to 80 kmph, our varied references in this product make us hopeful to aspire for further forthcoming urban metro projects in various cities..
Key advantages Of Pre- cast Plinth:- Provides environmental construction and it reduces obstruction to traffic as everything is factory made and onsite work is bare minimum.
- Productivity is very high
- Quality and finish is better than cast in situ
- Capability to provide pre-assembled fastening from factory
- Proven design on curves
- All technical approval and specifications in place.
2.Patil RHEDA:
The advantages of using PATIL RHEDA Ballastless track systems include long life cycles, high speeds ride comfort and great load-carrying capability. Practically maintenance free, ballastless track systems ensure 100% availability over many years. In many cases, a maintenance-free track system is indeed the more cost-effective solution over the long run. The use of PATIL RHEDA sleepers is ideal for laying washable aprons at railway stations thereby improving the cleanliness of the station yards. The station aprons where the PATIL RHEDA sleepers have been implemented include Bhubaneshwar , Kacheguda, Surat etc.,
3.Patil PORR BLT:
The Porr system was designed to replace the typical behavior of the ballasted track by several elastic elements in the ballastless system. The typical behavior of a ballasted track shows the elasticity in the ballast itself and in the rail fastening system. These two elastic elements have to be copied by the elasticity of the rail fastening system in the ballastless track and of the elasticity of a second layer which is situated at the bottom of the prefabricated slabs. This system leads to a distribution of the elasticity between the elastic coating of the slabs and the rail fastening system of 10% to 90%.
