Customer Requirements
Points operating equipment is used to safely change the lie of railway turnouts to allow trains to change tracks. Traditionally, points operating equipment is located in the spaces between railway sleepers, which hinders the use of automated track tamping machines and ultimately results in long term maintenance and reliability problems.
Siemens worked with Queensland Rail (QR) to introduce a new points operating system called One Trough (S 700 VA) which eradicates this problem.
Solution
The Siemens S 700 VA points operating technology was specifically designed to suit the needs of the Australian railway market and, being a local innovation, it is a highly cost-effective solution for our customers.
The One Trough Points Operating System (S 700 VA) is a complete in-sleeper points operating system whereby all equipment is installed into hollow sleepers (also called troughs) in place of normal sleepers. The troughs provide secure housing of the points operating equipment and incorporate the points machine as an integral component, enabling the use of high production tamping machines through the turnout area and providing improved maintenance benefits and enhanced stability.
Benefits
- Removes points operating equipment from between the sleepers.
- Points operating, locking and detecting equipment all installed in a single trough sleeper.
- Simple, proven and reliable claw lock rail-head locking or advanced VAE Spherolock locking system.
- Low maintenance intervals with less maintenance and lower life-cycle costs.
- Permits automatic tamping through out the turnout.
- Improves track stability.
- Suitable for single drive turnouts, multiple drive turnouts and swing nose crossings.
