An official investigation has recommended safety improvements to Sheffield's Supertram network after two teenagers were struck by a tram at a crossing last June, leaving a 15-year-old girl seriously injured. The Rail Accident Investigation Branch (RAIB) found the pair had not seen or heard the tram approaching and concluded that risk management by South Yorkshire Mayoral Combined Authority (SYMCA) and South Yorkshire Future Trams Ltd had not been sufficiently effective, prompting calls for a wider review of crossing safety across the network.

The collision happened on the Staniforth Road crossing at about 16:15 BST on 22 June last year, as the teenagers, on a cool-down run after competing at a nearby athletics stadium, turned onto the crossing with only about a second's warning before being hit. The tram was travelling at 17mph, below the 30mph limit, and the driver braked and sounded the horn too late to avoid impact; the report also noted a raised cobbled surface beyond the crossing may have worsened injuries. The RAIB has recommended a full risk assessment of high-risk locations across the tram network and greater consistency in the use of audible warnings, and SYMCA said it would carefully consider the findings while maintaining that safety remains its highest priority.
