Tuesday evening commutes along the R Line took a hard turn when RTD abruptly suspended train service at Florida Station because of a reported security issue, leaving trains held at nearby stations as space allowed. H Line trains were rerouted to turn and depart from Nine Mile Station until further notice, interrupting service up and down the I-225 corridor and tangling trips through Aurora and southeast Denver.
RTD announced the suspension on X, saying a security issue at Florida Station had prompted the stoppage and that trains were being held while staff responded, according to RTD. The agency did not release any additional information about what specifically triggered the security concern.
Rider impact and alternatives
The pause is expected to slow things down for southbound riders along the Southeast/I-225 corridor, with knock-on delays likely for anyone trying to transfer between lines. RTD has previously filled similar gaps with bus shuttles and alternate train routings. During earlier maintenance work, for example, the agency set up bus bridges between Florida and Southmoor stations and local coverage urged riders to keep an eye on service alerts and the NextRide app for real-time options, according to the Denver Gazette.
Where this happened
Florida Station, near Florida Avenue and S. Abilene Street, serves both the H and R lines. Nine Mile Station at 3181 S. Parker Road is a major Park-n-Ride and transfer hub on the I-225 branch. RTD lists both stops as focal points of the current disruption on its facilities pages, per RTD.
What to watch next
RTD said the situation is ongoing and did not give a timeline for restoring full service. Riders are being urged to monitor the agency’s official channels for updates. This story will be updated when RTD issues an all-clear or releases additional details.
