The City Loop first opened in 1981 and has become a core part of Melbourne's train network.
We want to celebrate this milestone as we look ahead to the completion of the Metro Tunnel.
Perhaps you worked on construction of the City Loop or at one of the new stations? Perhaps your parents or grandparents did?
Were you one of the first visitors on an open day, or did the City Loop change the way you travelled to work, school or shop? Maybe there's some old photos or home movies at the back of the cupboard?
