In the early days of New Zealand rail, the Johnsonville line was the only way out of Wellington (unless you wanted to go via the Hutt Valley and the Remutaka Hill). But in the 1930s a new line was pushed through the Ngaraunga Hills and Johnsonville became a dead end.

Seventy years later, as part of an English paper at Victoria University, I put together a radio documentary on the Johnsonville Line, imaginatively called A Day on Line and it played on RNZ as a Spectrum episode some time in 2001.

(Historical note - the interview with the rail historian was recorded on the morning of September 10, 2001, as the first news of the Twin Towers attack was coming in.)
