It is 70 years since the former Belfast and County Down Railway was closed down as part of a short-sighted "rationalisation" of our rail network.
However, it has emerged that officials actually considered reinstating the line linking Belfast to its eastern hinterland in the 1990s.
Robert Gardiner, a railway enthusiast, stumbled across the plans when he acquired the original feasibility study from a former NIR employee.
Had they acted on the plan harassed commuters from Dundonald and other places travelling by car and bus could now be letting the train take the strain.
As missed opportunities go, this one takes some beating.
