Talk:Maglev Era/@comment-76.123.200.66-20170210191949

I have three mag lev tracks. I am getting "Cornelius hasn't researched Mag Lev era" when I try to send  mag lev trains to him. I remember getting similar messages earlier when I opened the first mag lev track but can't recall how to do that and haven't found any way to research it. Suggestions?
