[3] On August 31, 2009, the Route 6 began Midday service between Edmondson Village and City Hall.

During the midday the route 6 was scheduled to operate every 22 minutes, yet in reality it was common to see two 30s at a time.

The 30 continued to serve the former 6's western routing, to Edmondson Village via W. Baltimore St.(supplementing the 20 bus), while adding service in East Baltimore by mimicking the 10 bus east of Charles Center to its layover on the Johns Hopkins Bayview Medical Campus(the 10 bus bypasses Baywiew, continuing SE toward Dundalk).

Unlike the former 6, which was local, the qb46 is limited stop, and allows passengers to get to Cedonia and Catonsville much faster than the 5, 6, and 10 buses could.

[2] In February 2015 as part of a Bus Network Improvement Project the 30 was discontinued and all West side peak day service transferred to the 20.
