SBB seeks cost savings with Sinet interlocking

摘要

Traditionally controlled limitations on the distances between signals and points and the point-to-point cabling of the field elements has underpinned the cost of constructing and operating electronic interlockings. These technical specifications, which have previously been difficult if not impossible to change, limit an interlocking area to a maximum of 13km. As a result remote computer locations are deployed to cover longer distances, which require the construction of numerous equipment buildings to house wayside interlocking equipment, and its associated power supply and air-conditioning systems. Such installations inevitably increase costs, with cabling, cable ducts and cable distribution racks accounting for 20-30% of the cost of the entire interlocking.
