The Metro Tunnel doubles the size of Melbourne's underground rail network and represents a significant expansion of the network since the City Loop tunnels opened in 1981.

就在周二下午，Metro Tunnel 发布了一份声明。声明中明确指出，如果有人在 State Library Station 刷卡进入后，步行至连接的Melbourne Central Station再刷卡离站，系统会把这一行为视为一次乘车行程，按普通票价进行扣费。
