During construction of the tunnel, a crossing loop long enough to accommodate 116 wagons and a temporary connection to the now closed section of the Wairarapa Line were built to enable work trains to bring in materials and supplies.

[6] On 14 November 2009 the Rimutaka Incline Railway excavated the back of the second (disused) platform to both retrieve fill and to make way for the formation of their own rail yard.

At the top of the access road, where it meets the formation, the remains of the Dry Creek Gully bridge which carried the line over a washout, are to the right but obscured by dense foliage.

The trust proposes to reinstate the world-famous Rimutaka Incline, with its base of operations established at Maymorn, and is currently working through stage one of the project including preparing the yard, construction of buildings, fencing and platelaying.

[8] A 2011 strategy published by the Upper Hutt City Council proposes extending electrification to Maymorn, to capture planned growth in the area.

[10][11] On 23 July 2009, the locomotive and first carriage of a Masterton-bound Wairarapa Connection derailed after hitting a mudslide at eastern exit of the 572 m (1,877 ft)-long Maoribank Tunnel No.1, about a kilometre west of the station.
