Free space: improving capacity using intelligent infrastructure analysis and vehicle design

Historically Static Gauging has facilitated the safe operation of railways throughout the world providing a Gauge Line that both the infrastructure and rolling stock is designed to, however it is inherently over conservative as it assumes the maximum vehicle movements. In practice, maximum vehicle dynamic movement do not always occur. This can place unnecessary restrictions upon infrastructure builders and can result in manufacturers building trains smaller than they need to be. Absolute gauging applies accurate modelling of both the infrastructure and the rolling stock to calculate a more realistic view of the space. Understanding the relationship between the infrastructure and the vehicle as it travels through each structure makes it possible to deliver more useable space for the vehicle manufacturer. This additional space may be used to increase capacity of the rail network through design of larger rail vehicles or increased speed without the need for costly infrastructure enhancement, improving capability for free. Absolute Gauging has been used within the UK over the past decade and more recently has been developed further to provide Gauge Lines for specific projects (Intercity Express Project - IEP). Dynamic Gauge Lines are also applied to achieve a more realistic view of clearances. This has provided additional space for vehicle design and saved significant amounts of investment on infrastructure upgrade projects.
