[1] In 1901, two prototypes were built by the Randwick Tramway Workshops.

Deemed a success, a further 200 were built by Clyde Engineering and Meadowbank Manufacturing Company in 1902/03.

They were introduced for the electrification of the Eastern Suburbs lines, but also operated services on the North Shore lines.

[2] Withdrawals commenced in 1934; two pairs (499+500 and 529+530) were fitted with track brakes for the Neutral Bay service, with 529+530 lasting in service until 1955.
