L Line (RTD)

The Central Rail Extension Mobility Study Final Report[4] proposed that the D Line stations from 20th & Welton to 30th & Downing and future extension stations be operated on an independent route. This route would operate from the downtown loop to a new terminus created by sharing the A Line's 38th & Blake station.[5] Former D Line riders would have to transfer to the new L Line as the D Line's new northern terminus would be the downtown loop (nominally 18th & California station). The 14th & California station closed in 2004 could be restored to support the L Line at the Convention Center, allowing for transfers to Theatre District–Convention Center station.[4] RTD's Board of Directors approved the introduction of the current shorter version of the L Line with the January 14, 2018 service changes. The L Line uses existing track between 30th & Downing station and the downtown loop.[6]
