The author, Head of Section at the S.N.C.F. Equipment Department, relates the history of this laboratory since it was built by the former Northern Railway. He describes its present arrangement and states its purpose which is not research but essentially the verification of equipment, tests, investigations. This work is in principle confined to S.N.C.F. signalling and telecommunications equipment. Activities have been grouped as a result of the reform of S.N.C.F. structures. The author then describes the laboratory equipment and its use as regards electronics, photometry, relays, track circuit testing with simulators (high speed, information), and the testing of telecommunications and electronic equipment, computer functioning, etc. He then gives facts about the laboratory's mobile equipment which enables readings to be taken at any point in the installations, in particular 10 testing coaches, a power coach taking current directly from the 1,500 V supply, and an experimental railcar.
