A Beyer, Peacock & Company steam tram of 1885 was sent to Australia in 1886 as a trial unit by the New South Wales Government Tramways (NSWGT) for comparison against the Baldwin steam tram. The Baldwin design prevailed and this engine returned to England in 1889 to become Beyer Peacock works shunter No. 2. The engine is rumoured to have fallen into the sea on its return voyage,[2] but it survived and is still in working order and known as 'John Bull'.[3] Some sources show it as numbered '47' in Sydney, but number 47 had already been allocated around 1883.
Design
The steam tram motor is essentially 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
Sydney Steam motor and trailer car, 1879
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 in 1894, when the tramway's length reached 40 mi (64 km) when there were over 100 steam trams in service. In 1905-6 steam tram routes were replaced by electric trams, with the former gradually relegated to outer suburbs.
(***) Numbers 70 to 75 were six 'Baldwin-Downe' steam motors, delivered 1883-1884, that were first bogies of combined motor-passenger cars known as 'Jumbos'.[5][13][14]
Demise and preservation
The last NSWGT steam motor was withdrawn from service in 1937 and replaced by a trolley bus service. Preserved trams are:
Steam Tram Motor No. 1A, owned by Powerhouse Museum[15] The number '1A' was applied by the Powerhouse Museum. It is actually Steam Motor 28a of Henry Vale & Co. Makers number 52.[16]
