The R\u00e9seau Express M\u00e9tropolitain (REM) <\/em>uses a 1,500 Vdc traction power system supplied by an overhead catenary system (OCS) on its 67-km long track network. <\/mark><\/strong><\/p>\n\n\n\n

Stray currents and electromagnetic emissions produced by the traction power system and by the rolling stock traction system could create damages or interfere with the operation of infrastructures and equipment located in their vicinity (aerial and underground public services networks, structures, etc.) if adequate protection measures are not put in place.<\/p>\n\n\n\n

The REM track network crosses or is parallel to Canadian National (CN) Railway at many locations.<\/p>\n\n\n\n

SYSTRA Canada\u2019s mandate was to ensure that adequate measures were planned by the REM to protect CN facilities and that they would be implemented at each location where the REM track network is in proximity of CN facilities. Includes.<\/p>\n\n\n\n

More specifically, SYSTRA Canada\u2019s mandate consisted in:<\/p>\n\n\n\n
