The preserved line begins at the northern end of the
Lepperton Railway Yards (just past the main line turnout) and continues parallel to the
Marton - New Plymouth Railway for a few hundred meters before turning right at
Sentry Hill towards the
Waiongana Stream. After crossing the stream the line runs to the former
Waitara Road station and former Waitara Taranaki Co-Operative Dairy Company buildings at Brixton. The line continues from here towards Waitara, passing underneath
State Highway 3 at Big Jim's Overpass. Finally, the line drops into the Waitara Valley and into the township of Waitara proper, finishing just before the
Waitara River. In Waitara, most of the infrastructure is gone with only the main line and one loop remaining in the yard. The former Tahora station has been relocated to Waitara Road, where the society's rolling stock is stored. The site of the Lepperton railway station & yard is still owned and operated by
KiwiRail, where the station building was removed in 1994. The branch line has 8 level crossings along its length, all of which are protected by compulsory stop signs. Issues with these were raised in the community in 2004 as legally traffic has to stop even though trains seldom ran more than once a month. The Land Transport Safety Authority (now
NZTA) would not allow
Give Way signs and reinstating bells and lights had been reported as costing over $250,000 per crossing (almost the purchase price of the entire line in 1999) making installation unlikely for foreseeable future. Rail operations have become more frequent since then but motorists failing to stop for the societies trains is still an issue. == Operation ==
