Ineco Design Complex Birmingham Delta Junction for HS2 Rail Project Using Bentley Software
MicroStation Connections Innovator of the Month Pick for December

Firm Works Faster, Smarter, and More Effectively with Bentley’s Rail Solution

Preliminary design of the Birmingham Delta Junction – the new HS2 high-speed rail line connecting London, Birmingham, Manchester, and Leeds at a maximum speed of 400 kph.

Allow movement of trains in all possible directions every three minutes – at a commercial speed of 350 kph on the mainline and 230 kph on the turnout – without interfering with each other.

Enable a geographically distributed team of engineers and designers to collaborate efficiently on one of Europe’s most important ongoing railway projects.

From the start, it was clear that the design of the Birmingham Delta Junction for the United Kingdom’s High Speed Two (HS2) railway project would be a complex endeavor. HS2, a new high-speed line ultimately connecting London, Manchester, Birmingham, and Leeds, will offer more seating capacity, 50 percent shorter journeys between cities, a better passenger experience, positive environmental effects, and significant economic benefits including job opportunities and regeneration across the U.K.

“The project involves the preliminary design of a double track capable of a maximum speed of 400 kph and a commercial speed of 350 kph, as well as a large delta junction with many intersections,” explained Fernando Tejedor, senior project manager and railway team leader at Ineco, a global leader in transport engineering and consultancy awarded the project by HS2.

Ineco used Bentley software to model the terrain, design the optimal track alignment, integrate its geographically distributed design team for efficient collaboration, and generate the required documentation for this key project, within the challenging six-month time period.

A Complex, Multi-stage Project

The HS2 rail project is arguably the most important ongoing railway project in Europe. HS2 will be designed and constructed in three phases: 1) the development of a London-Birmingham connection, 2) further connections to Manchester and Leeds, and 3) connections to Glasgow and Edinburgh. The design of the Birmingham Delta Junction is particularly complex due to the fact that the main line needs to connect with branches to Birmingham and Leeds at this location.

In addition, the junction had to address each of the 21 points of conflict with associated infrastructure that include five motorway crossings, various high voltage power lines, river and canal crossings, plus minor roads and an existing conventional railway. “From a technical point of view, the Birmingham Delta Junction is the most complex corridor of the first phase of HS2,” explained Tejedor. “These connections produce a very complex operation scheme, allowing the movement of trains in all possible directions every three minutes – and at 400 kph – without interfering with each other.”

Ineco conducted two studies to develop innovations critical to the new railway:
