提高铁路基础设施的资金city

Author:Staff

With thousands of commuters into the capital city every day, additional trains into London are a plus to help with the heavy traffic congestion.

As part of the Brighton Mainline Upgrade Programme, an additional six trains per hour will be made available during the morning peak. Along with this, the programme would also see four additional services into London with a further two additional trains in 2043. Performance will also be improved through the segregation of flows and contribute toward additional train paths on the route.

Topographical surveys are required for this complex and extremely busy piece of London’s railway infrastructure. The programme provides the ideal time to upgrade to newer, faster and more efficient solutions for data capture.

负责该计划的政府实体网络铁路转向阿特金斯进行调查。

A major upgrade

Established in 1938, Atkins is one the world’s most respected design, engineering and project management consultancies. Working closely with a wide range of clients from different sectors and regions across the public and private sectors and local and national governments, Atkins delivers long-term trusted partnerships to create a world where lives are enriched through the implementation of ideas.

总部位于英国萨里的克罗伊登（Croydon）的阿特金斯铁路部（Atkins Rail Division）使用Leica Geosystems测量设备已有近20年的历史。该决定是去年决定取代咨询公司（Leica System）1100和1200个电台的大多数值得信赖但老化的车队，并使用最新的Leica Captivate Solutions增加了公司现有的GNSS，数字级别和遍历设备。bob apple

这次重大升级看到了广泛的工具：

• 1 Nova MS60 MultiStation
• 7 Viva TS16i Imaging total stations
• 4 Viva GS14 GNSS Smart Antenna
• 10 Captivate CS20 controllers
• 2个CS35 CS35平板电脑
• 2 LS15 auto focus digital levels
• 8 full traverse kits

With the new portfolio, Atkins was ready to take on the important rail project.

Site limits and challenges

To enable the additional programme paths toward London Victoria and London Bridge, there was a requirement to segregate flows at Windmill Bridge Junction. It would support performance improvement on the route through the segregation of key train flows, which currently transfer reactionary delays across the other adjacent lines and the wider South London network.

To achieve additional train stopping capacity at East Croydon, there was a requirement for additional platforms to be constructed. In addition to safely delivering a 12-car train operation between Selhurst and Gloucester Road Junction, infrastructure was required to accommodate a 12-car train on the Selhurst Spur.

结果，开发了可行性选项以实现这些输出。选项包括：

• Grade separation of Windmill Bridge Junction,
• Extension of the Selhurst Spur
• 风车桥交界处和东克罗伊登之间的其他轨道
• Two additional platforms at East Croydon.

It was identified that work would be required at East Croydon station to safely deliver the required passenger access to new platforms and provide sufficient increased passenger capacity on the concourse.

“As with all railway topographical surveys, the limitations of site access and the nature of railway infrastructure constrains the way we conducted the survey,” said Matevz Groboljsek, Atkins Track Team project manager. “This was especially true on a project area of this scale and considering the complex junction and train routing available through the section of the infrastructure.”

With accuracy and reliability paramount in the rail environment, Atkins turned to Leica Geosystems’ solutions and technology to avoid costly downtime during expensive and time restrictive track possession. The latest innovations available within the new Leica Captivate range proved invaluable in this situation.

The Leica Nova MS60 MultiStation, with its wide spread of functionality including the ability to scan up to 1,000 points per second, was used on the project. Combined with the imaging capability on all the total stations and the interoperability of these with both the Leica CS20 controller and CS35 tablet computer, this enabled Atkins to capture every necessary detail in the quickest and most effective way.

GNSS智能天线使用相同的控制器和迷人软件，以使用HXGN SmartNet校正服务快速准确地建立控制。除了迷人的软件外，还使用了最新的LEICA LS15数字级别，具有成像和自动焦点，从而可以在恶劣条件下更快，更准确的员工阅读。这些仪器还与轨道巨魔一起使用，并与Leica Geosystems激光扫描解决方案一起使用。

The provision of topographical survey data and selected point clouds for the project designers to use and develop created a rationalised railway infrastructure design that will increase capacity on an already packed section of South London’s rail network. Ultimately this will declutter historical track alignments, making them suitable for rail expansion into 2020 and beyond.

The project and the data provided to it will lead to providing a better railway experience for the growing customer base and will be used to support economic growth of the surrounding areas.

Providing topographical surveys to London’s railway infrastructure

对于阿特金斯来说，Leica Geosystems Solutions为该项目带来了许多好处。

Groboljsek说：“通过采用Leica迷人的软件技术，我们可以为网络导轨提供快速准确的数据实现，避免昂贵的回报，并节省时间和精力，同时也降低了风险。”“通过使用Leica GeoSystems解决方案的组合，可以安全，准确，有效地收集数据，尤其是在轨道访问权限期间的有限时间内收集数据。减少在赛道上的时间降低了基于现场的风险，并减少了对阿特金斯人员受伤的风险。此外，网络铁路财产和基础设施的风险降低了。”

Primary and secondary control was established using the fast and accurate Leica Viva GS14 GNSS Smart Antenna, using both post processed and live RTK data from HxGN SmartNet. The service was also used to increase efficiency by assuring the quality of 3D GNSS data directly in the field.

With intuitive and understandable software in the field and in the office, Captivate allowed instant 3D visualisation of the survey data collected on the railway site, providing a detailed understanding of the project requirements.

The Leica ScanStation P40 laser scanner also offered a fast scan rate with less noise and clearer scans along with streamlined workflows from the field to office and back via easy automated processing with Leica Cyclone laser scanning software. This was then all quickly and easily communicated to all staff and to the client using Leica TruView.

完成后，Brighton Mainline升级计划是第一个在项目生命周期中更早使用地形调查的研究之一。结合Leica Caintivate Solutions，铁路项目的交付顺利进行，使设计团队和测量师可以根据即时反馈主动管理和传输决策。
