А дальше в конструкциях вся линия была построена? Тоннели/лотки/мосты

Everything up to this point was 100% ready during the summer of 1985 and the inauguration was also planned for 23 September 1985. It was a few days before all this was cancelled.
To describe the whole history here would be very exhausting. Let's stick to the fact that a lot was designed, sometimes partially built and never finished, or completely built and only much later or never put into operation.
This is also true on the existing lines, where attentive travellers can see the rough construction of ghost stations on a daily basis.
One consolation: in Antwerp, there are such stations.
