Piers Total distance covered 72 KMTotal no. of piers 2748Piers in corridor – I 1109Piers in corridor – II 588Piers in corridor – III 1051Piers completed till now 1635

Piers

Bearings

• Bearings are used for resisting the rotatory loads

Bearings

Pre-Fabrication

• Piers hold the viaduct, this is done by stringing and sticking the Segments together.

Segments

Gantry and Travel for Lifting andLoading Segments in the Yard

Pre-Cast Segments

• In gen, 10 Segments between 2 Piers, each Segment about 40 Tons.• Placing Viaduct Segments with the help of Launching Gantry.

Station Concept

• The Stations, being windows to the Metro Service, are tastefully designed reflecting local culture.

Station Concept (Contd.)

Station Design

• Stations are covered by an overlapping roofing system, open at sides, covering the platform

• Staircases & Escalators designed based on • Architectural Elements • Functional Aspects.

Rolling Stock

• LTHMR has given Rolling Stock contract to Hyundai Rotem Company (South Korea).

• Total 57 Three-Car Train Sets.Measurement of car

Interior view

• LTHMR has given the Communication Based Train Control (CBTC) system to The Thales Company .

• Thales will Design, Build, Deliver and Manage the installation of the fully automated CBTC.

Summary

• Faster : - Journey Time Reduced

• Greater traffic capacity equivalent to:• 7 lanes of Bus Traffic (or) • 24 lanes of Car Traffic

• Low Energy Consumption per Passenger Km:• 20% only in comparison to Road-based

Systems.

• Eco-Friendly :• Air Pollution Nil• Sound Pollution Negligible

Development never ENDS
