I found this which has a slim chance of being related. Could it be the family with James Barrowman HENDERSON in it ?

CASUALTIES.
A man named John Henderson, aged 58 years, a carpenter, was killed at the Dunedin Railway Station on Monday. Deceased, who had been employed in the railway service for about seven years, and who lived with his wife and three daughters at Rankeillor street, South Dunedin, was instructed by Mr Pearson, one of the foremen in the Works Department, to adjust and robed a buffer stop post in the northern carriage shed, and he "commenced the work of excavation on Saturday last. Yesterday morning he resumed the work, and guyed the post with ropes on the western side, but the same precaution does not appear to " have been taken on the opposite side, deceased, who was working alone, was evidently in the act of coming out of the excavated hole, when from some unexplained cause the heavy post and strut fell upon him on the guyed side, pinning him to thİ earth, and killing him, it is supposed, ii:stantly. Deceased was found at noon by a youth named Thomas White, a carriage cleaner, beneath the post, quite dead, the post lying across his shoulders and crushing his chest against the western embankment. Dr Gordon Macdonald, who was called in immediately after the discovery, attributed death to a crushed chest, and the body was removed to the morgue.
