Yesterday, the trolley tracks at the rt 11 and CSX crossing began to sink below the railroad tracks. Therefore, the rt 11 trolley is short turning at Island Ave, and shuttle buses are being provided between that point and Darby Transportation Center. Also, the 13 trolley is not serving Darby terminal either. Rt 13 Darby trips are in place for access to Elmwood depot and to minimize deadhead times. Now, trolleys will have to access the 13 via 49th St and 58th Sts. CSX is responsible for this crossing, and should have it fixed by Friday.
