France's transport ministry will unveil new plans on Thursday for an express train service between Paris and Charles de Gaulle airport after several years of delays, a source close to the ministry said.
The so-called "CDG Express" line, conceived in 2000, was stalled because of strained government finances after construction group Vinci pulled out in 2011.
Weekly newspaper La Tribune's website reported on Tuesday that transport minister Frederic Cuvillier would announce that a state partnership had been given the task of putting in place the necessary funding.
"The minister will announce the resumption of the CDG project on Thursday," the source close to the ministry told Reuters news agency.
Charles de Gaulle, the biggest airport in France, situated in the north of the capital, is now served by the RER rapid commuter rail network operating in Paris and its suburbs, which is increasingly congested.
Last year Cuvillier said that the EUR€1.7 billion (USD$2.3 billion) project may be partially funded from new taxes on airline tickets that would raise EUR€400 million.
The project's infrastructure works are expected to be carried out by airport operator Aeroports de Paris and the French national rail network RFF before being handed to rail operators such as RATP or SNCF.
