RTD Service Modes

GDT > Reimagine RTD (GDT’s Version) > Service Modes

RTD’s services should be rebranded into the following modes:

Rail Services


– Single lettered following a 2016 study which indicated that most riders have little regard for the exact type of rail technology (“light” or “commuter”) they are travelling on.

Bus Services


– Double lettered from AA. Airport (“SkyRide”) services start with A.
– Stop spacing varies as most routes use highways.
– Operated with “over the road” coaches.

Rapid / BRT

– Numbered by adding 500 to the equivalent local route number.
– Stops every 0.3 – 1 miles.
– Operated with 60ft articulated buses.


– Numbered 0-499.
– Stops every 3 blocks.
– Operated with 30ft or 40ft transit buses.
