Local fans will already know this, but for out-of-towners who may be considering a trip to Philadelphia, the trolley subway will shut down for major rehab during the first half of August. Just how major may be broadly gauged by the fact that the trolley subway will be closed continuously from 10:00 pm Friday, August 1 through 4:00 am Monday, August 18, affording an extremely rare opportunity to ride and photograph actual trolley cars on the diversion trackage during daylight hours, including three consecutive weekends.
