A Birney or Birney Safety Car is a small light streetcar intended to be an economical means of providing frequent service at a lower infrastructure and labor cost than conventional streetcars.

[edit] Invention
The Birney car was the 1916 invention of Charles O. Birney, an engineer with the firm of Stone & Webster, an operator of a number of trolley systems in the United States of America in the early part of the 20th century.
The vehicle was a return to single-truck (single-bogie) streetcars. They were small and light, about a third the weight of conventional cars, of rugged standardized construction and inexpensively built. Twin motors gave them nimble acceleration.
[edit] Benefits
They were designed to operate with only a motorman, saving the cost of the conductor. The advent of World War I made single-person operation additionally attractive as it addressed the wartime labor shortage. When labor was available, the Birneys could be operated at more frequent intervals, prompting the slogan "A Car in Sight at all Times." This latter attraction was one of the street railway industry's first attempts to deal directly with automobile competition.
[edit] Decline
Thousands of the cars were purchased from their inception to a few years after the end of the war. They began to fall from favor because of the features that made them attractive initially. Their light weight could be a problem in snow that a heavier car could easily plough through, and ride was compromised or even derailment possible on poor track or from the efforts of determined youth. The limited passenger capacity rendered them unsuitable for busy routes and rush hour service, and the public began to deride them as flimsy.
The streetcar companies also found that the safety features of the Birney, such as the use of interlocked doors to prevent the car from starting if a door was open or a passenger was stuck, could be incorporated in larger cars and that the public was not as disturbed by the absence of the conductor as the companies had feared.
[edit] Continued use
Their initial rise and fall notwithstanding, the Birney car was useful and durable, and many were shipped to other countries, especially those in smaller cities and towns, where they served for additional decades. For example the city of Haliax, Canada bought up Birneys from other systems across North America to build an "all Birney fleet" and keep its streetcar system going in the difficult years of the depression and World War Two.
A number of Birney cars remain in use today in North America at trolley museum and heritage streetcar operations.
In Australia, seven Birney cars have survived in operating condition: five are at Bendigo Tramways, one at the Australian Electric Transport Museum, and one at the Hawthorn Tram Depot in Melbourne. Thus Australia has a high proportion of the world's surviving Birney cars.
