The line ran from the intersection of North Avenue and St. Paul Street to Curtis Bay, with selected trips to Energy Parkway and Riviera Beach.

[3] While all trips had operated from Curtis Bay, the line had two branches from downtown: one to the east along Monument Street, and one to the north to Roland Park.

And Route 64 started operating from Curtis Bay to downtown, with branches serving Wagner's Point, Maryland Drydock, Davison Chemical, and various other places in the area.

[4] Routes 63 and 64 that had been formed in 1977 continued to operate in this fashion until 1993, when changes started to be made.

In January 1993, Route 63 was modified to feed into the Patapsco Light Rail Stop rather than going to downtown Baltimore.

[5] Later the same year, when the light rail was extended further south, it was modified again to feed into the North Linthicum Light Rail Stop, and selected trips on Route 63 continued north to the Patapsco stop, replacing a branch of Route 64 that had served Linthicum.

Only 20 daily riders were using the service to reach Wagner's Point, requiring a taxpayer subsidy of nearly $20 each.

But this change was never implemented, and the line continued to serve Riviera Beach nine times daily.
