2.) Trackwork Installation - This works includes Flush Butt Welding of long welded Rail (LWR), Distribution of Materials, which includes precast concrete slab (where rails are mounted and fastened) and concreting. Gauge and alignment check prior to concreting.  

Production rates for flush butt welding up to 30 FBW / machine / day  Equipment - Flush Butt Welding Machine

Distriution of Material - Gantry Crane on Wheel or Forklift

Guage and Alignment Checking Equipment, Concrete pump.

3.) Overhead Lines (OHL) if electric driven
