Incident Description

On Wednesday January 24, 2024 an RTD light rail train, operating a southbound “E” Line service from Union Station to Ridgegate Parkway, derailed on a “Hi-Rail” access pad located immediately north of Hampden Ave and approx. 1/2 mile north of Southmoor Station. The train consisted of 3x Siemens SD-100 units with light rail vehicle (LRV) #125 leading. The LRV began shedding wheel and tire components between Louisiana Pearl Station and University Station and the operator noticed “performance issues”. By Colorado Station, wheel and tire components were being shed at an increasing rate. The operator contacted Light Rail Control asking about previous reports of issues with that specific train from other operators and was told there were none. The train continued southbound from Colorado to Yale Station with “significant performance issues” and just south of Yale Station, experienced catastrophic failure of one wheel / tire assembly with another tire also being affected. The train finally came to a stop when it struck the “hi-rail” access grad crossing pad at Hampden Ave. There were no injuries. There was significant damage to alignment infrastructure, rolling stock and the wheel structure of the LRV.

Initial efforts to re-rail the leading LRV proved difficult due to the constrained nature of the site and snowfall. The LRV was finally re-railed on Monday January 29th and towed to Mariposa Yard.
