a Dj with the Christchurch to Greymouth passenger train on the Big Kowai viaduct, mid 1980s

In 1987 this train was replaced with the tourist orientated and highly sucessful TranzAlpine -- see the book On The TransAlpine Trail. 

This is a common photo location.  The zoom lens effect on the apparent size of the Torlesse Range mountains in the background was applied here.
