A trolleybus is an electric bus that draws power from dual overhead wires using spring-loaded trolley poles. Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole. They are also distinct from other kinds of electric buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there are exceptions.
The interurban is a type of electric railway, with tram-like electric self-propelled railcars which run within and between cities or towns. The term "interurban" is usually used in North America, with other terms used outside it. They were very prevalent in many parts of the world before the Second World War and were used primarily for passenger travel between cities and their surrounding suburban and rural communities. Interurban as a term encompassed the companies, their infrastructure, their cars that ran on the rails, and their service. In the United States, the early 1900s interurban was a valuable economic institution, when most roads between towns, many town streets were unpaved, and transportation and haulage was by horse-drawn carriages and carts.
The Presidents' Conference Committee (PCC) is a tram design that was first built in the United States in the 1930s. The design proved successful domestically, and after World War II it was licensed for use elsewhere in the world where PCC based cars were made. The PCC car has proved to be a long-lasting icon of streetcar design, and many remain in service around the world.

With the Port Authority's Transit Development Plan, many route names will be changed to its original, such as the 41D Brookline becoming the 39 Brookline. Many of the streetcar routes have been remembered in the route names of many Port Authority buses.

The Philadelphia trolleybus system forms part of the public transportation network serving Philadelphia, in the state of Pennsylvania, United States. It opened on October 14, 1923, and is now the second-longest-lived trolleybus system in the world.

The three surviving routes serve North and Northeast Philadelphia and connect with SEPTA's Market–Frankford rapid transit line.
