An independent investigation has been launched after a passenger train struck a portable rail grinding machine on the tracks near Redbridge, Hampshire, early on Tuesday morning. The incident, which took place around 06:17 on 19 May 2026, involved the first passenger service of the day on the Romsey to Redbridge Junction line.
Remarkably, despite the collision, there were no reported injuries to either the passengers or the crew onboard the train. However, the portable rail grinding machine was completely destroyed, and the train itself sustained damage, rendering it unable to continue its journey. Crucially, the train did not derail as a result of the impact.
The incident occurred after engineering work had been carried out on the line overnight, with the track having been 'handed back' for regular service shortly before the collision. The investigation will now focus on understanding the precise sequence of events that led to the train encountering the maintenance equipment on the line.
Investigators will also examine the actions of those involved and any influencing factors that may have contributed to the situation. Furthermore, the arrangements for managing equipment within 'possessions' – sections of track where engineering work is taking place – will be scrutinised, specifically concerning portable rail grinding machines. Any relevant underlying factors will also form part of the comprehensive inquiry.
This investigation is being conducted independently of any inquiries by the wider railway industry or its regulatory body, the Office of Rail and Road. The findings, along with any recommendations aimed at enhancing safety, are expected to be published upon the conclusion of the investigation, and will be made publicly available.
