Course Aims
This course is intended to provide a delegate with an in-depth knowledge in the surveying, calculation and design of track re-alignment schemes when using the “Hallade” method.
Learning Objectives
At the end of this course the delegates will: -
Have a clear understanding of track geometry and track parameters, speed, curve, gradient etc.
Be able to demonstrate a clear understanding of the principles of the “Hallade” survey, including the use of relevant surveying equipment
Have an understanding of the theory of overlapping chords
Be able to demonstrate an understanding of design requirements and the relevant tolerances
Understand the quarter chord theory
Understand the transition theory – cubic parabola
Have an understanding of the tangential changes of radius relating to the curvature of the track
Be able to demonstrate a clear understanding of the method of employing couples
Understand the relationship between a theodolite straight and Hallade curve
Be aware of the requirements for making the track for on-track machines
Be aware of Railway Group Standards, Network Rail Company Standards and D.O.T. requirements relating to track re-alignment schemes
Course Duration
Ten days, consisting of two continuous five day modules, Monday – Friday.
Pre-requisites
There are no particular educational or competence pre-requisites for the course. However, the following factors will benefit the delegates:-
Prior technical experience of working on the maintenance/ renewal of the track
Good numeric skills
Prior basic skills in surveying and use of equipment
Personal Protective Equipment
This course requires the delegate to be on or near the running line and therefore, he/she MUST be in possession of:-
Valid P. T. S. Card
Protective “all orange” High Visibility Clothing to BS EN 471:2003
Safety Footwear to BS EN ISO 20345:2004
Safety Helmet (white/blue) to BS EN 397:1995
General Purpose Gloves to BS EN388:2121
Certification
The delegate is required to complete an examination to demonstrate his/her ability to complete a survey and design scheme using the “Hallade” Method.
Re-certification is not required.
