Interior and Seating
RTD’s Siemens ‘SD-100’ light rail units feature ‘Knee to Knee’ seating. Following a lawsuit brought by the Colorado Cross-Disability Coalition, RTD agreed in 2017 to provide two ADA spots at each end of every light rail unit; for trains already in service, this was achieved by removing eight seats (16 per unit).
