Derrimut was a mid 1950s or early 1960s plan: obviously the rump of the unfulfilled Laverton project. Still, old plans never die, the get passed from senior to junior, and reappear as Tarneit link.
AFAIK the proposed road exit is using the alignment of the older planned line.
And now:I am the station immediately north of Richmond.
