Questions still unanswered on REM

A 202-page document about the REM was made public Monday but some basic details are still unanswered, like how much passengers will have to pay. A 99-year deal has been made but the Caisse de dépôt could apparently sell the whole thing anytime after 2028, although the spokesman says they don’t plan to sell it. Only the government is mentioned as a possible buyer: I don’t see anything stopping the Caisse from selling it to, say, a foreign investor or government.
