Track Access Services have been out filming in the South of England and Wales, capturing previously unfilmed routes on the UK rail network. Filming will continue throughout 2017, with complete UK coverage scheduled for the end of this year.
New footage captured over the past two weeks equates to 1326 miles - just over 6% of the total network, this is in addition to large sections of the network that have already been filmed.
Complete driver's-eye coverage of the UK rail industry is being captured for the benefit of rail industry users, providing virtual track visits and route learning material via a convenient and secure streaming platform.
Footage is streamed via Track Access Portal, an online distribution platform, providing users with forward facing in-cab video linked to moving locational maps. Routes are organised by Sectional Appendix Line of Route and can be linked to National Electronic Sectional Appendix (NESA) maps or third party maps.
Track Access Portal provides industry users with access from any internet enabled device via an individual or group login. In addition to interactive map functionality, footage can be enhanced with onscreen graphic overlays and commentaries for additional user information.
Track Access Services are commited to capturing complete UK route coverage and providing a convenient resource platform to benefit rail drivers and operators.
Software Enables Track Access Services to Create Complete, Accurate 3D Rail Models for Faster, Safer, and More Accurate Signal Sighting
Create a More Flexible Track Layout and Signaling System
Derby Station, located in the United Kingdom, currently handles 16 passenger trains in a typical hour and 30-40 freight trains per day using tracks and signals constructed many years ago. In 2014, Network Rail, the Derby Station operator, had a once-in-a-generation opportunity to create an improved track layout at Derby, in conjunction with new track and signaling.
The goal was to put in place a more flexible track layout and optimize signaling to reduce travel time for passengers, segregate traffic flows, reduce conflicting movements, and cut reactionary delays and average minute lateness. To achieve this goal – and meet new compliance requirements in the U.K. for desktop design capabilities – Network Rail turned to Track Access Services Ltd. (TAS), a Bentley development partner. Together, they created an innovative desktop-driven, 3D virtual reality modeling, and signal design process.
DB Cargo has been capturing high quality footage of the UK rail network and working in partnership with Track Access Services to provide a route learning platform that drivers can access via phone, tablet or computer.
Track Access Portal was developed to offer rail operators an accessible platform providing high quality video footage that runs alongside a moving map, whilst advising on other areas such as speed and signals. Using Track Access Portal gives the option to view routes multiple times and review certain sections of footage without visiting the live rail infrastructure.
As an immediate distribution channel, Track Access Portal can enable a faster, more efficient method of route learning. Route changes can be efficiently shared with drivers, in a cost effective manner.
Andrew Byrne, Head of Resources at DB Cargo UK, said:
“This has opened up huge potential for us and for the whole rail industry as it provides a more efficient and effective method for route learning and retention of route knowledge. We have had very positive feedback from our drivers and other industry stakeholders about the programme.
“We have filmed around 40% of the UK rail network, covering a substantial number of routes already. We are continuing our work so that we can roll out digital route learning even further.”
David Reed at Track Access Services Limited, said:
“The new web based delivery solution provides unlimited access for a variety of tablets and mobile devices. We are pleased to be working on this joint collaboration with DB Cargo UK, and see great potential for the rail industry using this technology."

SnakeGrid® (Local Coordinate Mapping)
Available For: Licensing and collaborative development
SnakeGrid®products provide innovative solution to a significant problem in engineering surveying, namely the design of a coordinate system that has minimal scale factor and height distortion even when projects extend for many hundreds of kilometres.
The Technology and its Advantages
SnakeGrid®, a registered trademark of UCL Business PLC, includes a range of bespoke and over the counter surveying solutions based on technologiesdevelopedin UCL Civil, Environmental and Geomatic Engineering Department.
SnakeGrid® products provide innovative solution to a significant problem in engineering surveying, namely the design of a coordinate system that has minimal scale factor and height distortion even when projects extend for many hundreds of kilometres.
When working on projects that extend a few kilometres, engineers and surveyors are accustomed to the concept of a local site grid that effectively makes a flat earth assumption. As projects grow beyond a few kilometres, however, it becomes necessary to introduce a projected coordinate system – and then all those working on the site have the problem of making scale factor corrections. If there is a significant height range across the project then there is the added problem of making reductions to sea level or any other standard reference height.
The SnakeGrid® solution provides a coordinate grid system that maintains a unity scale factor along a trend line that follows the project in and height. In this way, projects such as railways, highways and pipelines can extend for hundreds of kilometres can have a single seamless grid with a scale factor distortion less than a few parts per million along the whole project and for several kilometres on either side.
The SnakeGrid® family of products, a design service to produce the SnakeGrid®, software to transform between coordinate system and mapping of raster images and also provides the core SnakeGrid® functionality as a Dynamic Link Library (DLL) for integration into third party software.
Case study: Mobile laser surveys on Crossrail
In preparation for Network Rail’s infrastructure improvements to the Crossrail route between Paddington and Reading, Track Access Services were engaged to acquire accurate 3D data using a rail mobile survey which was conducted using terrestrial laser scanning. The data collected supported the design stages for the Crossrail project, currently Europe’s largest construction project, and set to link London’s main employment centers, ease congestion, and improve connections to mainland Europe by 2019.
A geo-tagged 3D point cloud and synchronized HD video was collected using a Topcon IPS2 scanning rig mounted to the front of a standard locomotive, running at regular line speed. TAS SnakeGrid tools were then used for data conversions:
