[2] The major engineering structure on the line was Whitacre Mill Viaduct at Deighton, which ran on a curve across the Huddersfield Broad Canal, a drain, and the River Colne for 177 yards (162 m).

There were no reports of injuries and the passengers walked to the main line junction where a passing train from Normanton stopped to pick them up and take them into Huddersfield.

[18] Fenay Bridge was built without a goods yard, something which was commented upon in the local paper, with a correspondent pointing out that the area was host to 20 mills within 1-mile (1.6 km) of the station.

By June 1916, a second platform had been installed on the west side of the curved line leading to the main Huddersfield to Heaton Lodge Junction railway.

It was used solely by people travelling from either Kirkburton, Fenay Bridge or Kirkheaton; workers from Huddersfield used the tram system.

During the First World War, the chemical works at Deighton sent out over 1,000,000 tonnes (1,100,000 tons) of acids and explosive, whilst a fireworks factory at Fenay, made over ten million hand grenades.

[25][26] The Kirkburton branch closed to passengers in 1930, with coal traffic from Lodge Mill Colliery ceasing in the same year.

[27][28] Other industrial concerns kept the branch alive for another 35 years, with the final train running on 2 April 1965, and closure coming three days later.

[29] After final closure of most of the line, a short spur through the old Deighton station was retained until February 1971 for traffic to a chemical works.

[30] A new station at Deighton opened up to traffic on 26 April 1982, on the northernmost lines of the old quadrupled track section between Huddersfield and Heaton Lodge Junction.
