Despite a budget shortfall, SEPTA will be able to resume purchasing hybrid diesel-electric buses thanks to two grants from the US Department of Transportation. For the first time ever, SEPTA will purchase hybrid 60-foot accordion buses, which are the longest buses in the system. SEPTA’s current assortment of hybrid buses is about 30 percent more fuel efficient than equivalent clean diesel buses.
SEPTA is the beneficiary of $15 million in federal funds to cover the difference in cost between hybrid and clean diesel 60-foot buses. Luther Diggs, who’s in charge of operations at SEPTA, says it will stretch out the acquisition of these longer buses over four years, with the first year’s purchase entirely hybrid. Over the four years, SEPTA will be replacing 155 longer buses, with an option for 65 more. The percent of these that are hybrid will depend on how much more grant money becomes available.
This opens the possibility that additional bus routes might see these longer buses. "We have some additional need for 60-foot buses," confirms Diggs. He suggests that the Route 47 bus, which was the subject of the
failed skip-stop pilot and more successful attempts to speed it up, might end up seeing longer buses. Also, he hints that the extremely well-traveled Route 17 bus, which runs up and down 19th and 20th Sts. in South Philadelphia and across Center City, might be another new candidate for the 60-footers.
Shortly after the $15 million grant was announced, the Federal Transit Administration (FTA) announced
another grant of $5 million to pay for additional hybrid 40-foot buses, the most prevalent of SEPTA's fleet. This is welcome news for many local environmentalists, who earlier this year were dismayed to hear that funding difficulties meant SEPTA would cease acquiring standard-size hybrid buses. According to Diggs, SEPTA will resume purchasing these hybrid buses in 2013, and only purchase hybrid 40-foot buses in 2014.
Diggs is convinced that hybrid buses represent the most financially sensible way for SEPTA to green its bus fleet. Diggs says SEPTA did examine running buses using compressed natural gas (CNG) in the mid-1990s. However, hybrid buses were ruled more effective than their CNG counterparts because of "infrastructure, residential neighborhoods, and cost," says Diggs. While some transit agencies in California and Texas use CNG, there are legitimate concerns about the cost of putting in CNG infrastructure and the health risks associated with natural gas.
