Those of the access, the ways and the exploitation with a dealer. The town council chooses in 1897 the general Company of traction, propriétré of the baron Édouard Louis Joseph Empain. The law of March 30, 1898 declares utility public "the construction of a metropolitan railway to electric traction, intended for the transport of the travellers and their hand luggage". The general Company of traction creates the Company of the metropolitan railway of Paris (CMP) in April 1899.
