The express bus will debut Sunday, covering about 10 miles between Frankford Transportation Center and the Neshaminy Mall. Its route is essentially the same as the Route 14 bus but is far more streamlined. The 14 bus makes more than 80 stops. The new Direct Bus will make only eight, reducing the length of the overall trip from 47 minutes to about 30. The express bus stops are the boarding or departure points for almost 50 percent of the Route 14 bus' riders.

A bus on the new service should come along every 10 minutes during rush hours and every 15 minutes the rest of the day and during weekend days, officials said.
