Rail Infrastructure Gauging Assessment

Gauging assessment is the exercise necessary to confirm that a train may operate over the railway without coming into physical contact with any of the railway infrastructure, or adjacent trains, when operating over the full range of speeds and loading conditions.

Gauging assessment normally also considers platforms stepping distances.

Gauging assessments may be required under a number of circumstances:

 Gauging Compatibility

AEGIS have built up experience of carrying out gauging assessments for different vehicle types across a range of circumstances. With a broad knowledge of routes and vehicle types, AEGIS can propose the most practical strategy to demonstrate gauging compatibility.

This is a choice between;

A key feature of any comparative gauging is the consideration of the features of the comparator stock, for which Aegis has the necessary knowledge to facilitate a suitable comparison with supporting justification.

Railway Infrastructure Electromagnetic Compatibility Studies

A failure in electromagnetic compatibility (EMC) can lead to system breakdowns, unreliability, and potential degradation of safety; affecting systems such as signalling, radio communications and rolling stock.

The electrically complex railway environment comprises various systems that have the ability to generate and/or be affected by electromagnetic disturbances.  

The introduction or modification of any such systems on the railway will generally require an EMC study to ensure high levels of reliability and safety remains after any change.

AEGIS are the perfect choice:

Vehicle Performance Analysis

There are a variety of circumstances in which vehicle performance may need to be considered in some detail.

Examples are:

In both these cases, as well as understanding timetable impact, performance may need consideration to confirm compatibility with signalling

AEGIS have detailed understanding of vehicle performance to allow evaluation of either the factors affecting performance or the impact of a vehicle’s performance.

Furthermore we are able to provide calculations to examine the performance of vehicles either generically, or on specific route profile sections taking account of gradients, curves and linespeed restrictions. This can allow a quantitative evaluation of options being considered for vehicle modifications or deployment.
