[1] Opened in 1924, the system gradually replaced the George Town tramway network.

It lasted until mid-1961, when it was closed and replaced by a network of motor bus routes.

[2] In 1934, two nine-seater trolleybuses were purchased specifically for the one mile Penang Hill Railway service from Lower station to the Air Itam main road.

In the 1950s the original fleet was replaced by 26 Sunbeams and five 1935 built AEC 664T double-deckers purchased second-hand from London.
