Just for the record the ferry companies are the ones responsible for the tunnel being only for trains. There were a few projects to choose from and especially one (MY grand dad's project, yes MY) which had fierce oposition from the ferry companies. "Cars driving under the sea by themselves for a small toll? ARE YOU MAD?" they said... So we got the trains...
