Top Structure and Slab Track |Tel-Aviv - Jerusalem Express Railway Line (1A)

Israel

An express railway line which offers a connection between Jerusalem, Ben-Gurion Airport and Tel Aviv within 28 minutes at a speed of up to 160 kilometers per hour. The line ends at an underground railway station 80 meters deep at the entrance to Jerusalem. A multi-disciplinary design and construction project (Design Build) that includes civil engineering: preparations for railway tracks and installation areas, production and laying of prefabricated concrete tracks, laying of tracks from Latrun to Jerusalem, construction of escape tunnels and service tunnels. Installation of electromechanical systems: electricity, low voltage systems, infrastructure for railway contractors, plumbing and fire extinguishing, air conditioning, ventilation and smoke removal. Maintenance of the systems for 10 years. This is the first logistical and engineering challenge of its kind in Israel. Working in narrow tunnels (built using the TBM method) tens of kilometers long, using dozens of teams at the same time. Daily transportation of workers, mechanical-engineering equipment, concrete mixers and other transportation vehicles within the tunnels. The project was carried out to world-class standards due to meticulous day-to-day planning and coordination, meticulous scheduling and engineering optimization, and the development of dedicated methods and solutions.
