Bealey River

In the first half of the 20th century, the New Zealand Railways Department (NZR) dumped a number of withdrawn locomotives and wagons in the river to stabilise its banks and prevent erosion, particularly near the railway bridge across the Bealey River. Some of these locomotives and wagons have been recovered by heritage groups with the aim of restoring them to operating condition, including WMR No. 9 (later NZR N 453) by the Wellington and Manawatu Railway Trust in 2003.[2] Most of the other locomotives and components have since been either buried or scrapped. The more substantially complete remains of ex-WMR No. 10 (later NZR N 454) are believed to be buried in the river bed near Cora Lynn, further up the river.

During the early 1920s, NZR used a former quarry near Cora Lynn station as an open-air workshop to strip locomotives of useful parts before they were dumped. This quarry was host to a number of locomotive parts including the frame of V 132, which had been retrofitted with Walschaerts valve gear in 1898 as an experiment by NZR. Shortly after this frame was salvaged in 1997–98, Tranz Rail and the Department of Conservation initiated a clean-up operation in the old quarry, burying many of the locomotive parts there into the access embankment.

Similarly, NZR used the Bealey River as a place to scrap old wooden passenger coaches in the 1950s and 1960s. These carriages would be brought from Addington Railway Workshops in Christchurch, shunted into the riverbed, and then burnt to recover their metal parts for scrap or as spares for other operating vehicles.
