History

Steam trams were introduced when four steam tram motors imported to Sydney as a temporary transport for the International Exhibition of 1879. It was built at the Baldwin Locomotive Works, Philadelphia, U.S.A. and hauled double decker trailers conveying passengers from the Redfern railway terminus to near the Botanic Gardens

Beyer Peacock Steam Tram No 2464 of 1885 was exported to Australia in 1886 as a trial unit by the NSWGT for comparison against the Baldwin steam tram. The Baldwin design prevailed and this engine returned to the UK in 1889 to become Beyer Peacock works shunter No.2. The engine is rumoured to have fallen into the sea on its way from New South Wales to Manchester, before delivery to Beyer Peacock.

Design

The steam tram motor is basically a small enclosed saddle tank locomotive steam motor with four driving wheels in an 0-4-0 arrangement. A wooden cab encloses the entire locomotive, which features five windows along each side. Access to the cab is through doors from either the front or back platform. The tram is powered by an orthodox locomotive type boiler, American bar type framing, conventional "D" type slide valves and spring suspension. Coke and later coal was carried in a bunker on the rear platform and water in the semi-circular saddle tank.

Typical specifications for an 11" Baldwin steam tram motor:

  • Cylinders: 11" diameter x 16" stroke
  • Tractive Effort: 120 psi steam, 5,500 lb at 10 mph
  • Weight: 14 tons 2 cwt
  • Length: 17 feet 2 inches
  • Width: 8 feet 6 inches

    • Service

    The Redfern to Botanic Gardens tramway was planned to operate for the duration of the exhibition. Proving so popular an extension to Randwick was opened in 1880. The peak of steam working was reached during 1894, when the length of the tramway reached 40 miles (64.7 km) when there were over 100 steam trams in service. In 1905-6 steam tram routes were replaced by electric trams with steam trams gradually relegated to outer suburbs.

    Steam Tram Motors in service were:

    Demise and Preservation

    The last NSWGT steam motor was withdrawn from service in 1937 and replaced by a trolley bus service. Preserved trams are:
