APPENDIX A - MECHANICAL REQUIREMENTS FOR THE
INSTALLATION OF SRS SYSTEMS ON BOARD A TRAIN
A.1 - Introduction
This section deals with the installation requirements for the use of a georadar
(GPR) system on-board a train.
The system consists of:
• a notebook computer
• a battery
• a GPR control unit
• a GPR multiplexer unit
• up to 4 GPR antennas
• an odometer
• and relevant connection cables.
Items 1-4 will be mounted inside the locomotive and don’t need any specific
installation; on the contrary, items 5 and 6 shall be mounted in the front of the
train and require some mechanical arrangements.
For practical reasons (mainly logistical), some of the devices needed to assure the
proper mounting of the system should be provided by SNCF; basically, these
consist of a metallic frame used to house the antennas and the brackets for fixing
this frame to the front of the locomotive.
A.2 - Mechanical requirements
Mechanical installation of the antennas and the odometer requires brackets to be
fixed to the buffers of the train. Therefore, it is important that the train used for the
test has buffers.
Moreover, it is also important that there are no obstacles between the buffers as
measurements would be affected by them (see Fig. A. 1 ).
