On 13 October 1874, the first section of the Palmerston North - Gisborne Line opened between Napier and Hastings. Over the following 17 years the line steadily extended into the Hawkes Bay interior, and on 9 March 1891 it opened through the Manawatu Gorge to Palmerston North. Construction of the Wairarapa Line from Wellington was steadily advancing towards its junction with the Palmerston North - Gisborne Line at Woodville, at the eastern, Hawkes Bay, end of the Manawatu Gorge, but the only rail access to Wellington at the time was via the Wellington and Manawatu Railway Company's line (WMR) up the west coast between Wellington and Longburn, just south of Palmerston North. The Railways Department introduced the Napier Express as a dedicated passenger service between Napier and Palmerston North, with connections to the WMR for passengers to Horowhenua, the Kapiti Coast, and Wellington. This was a significant upgrade for passengers on the Napier line, as services had previously just been slow mixed trains, carrying both passengers and freight.
