The Pacific Electric Railway strike of 1903 was an industrial dispute between Mexican tracklayers and their employers on the construction of the Main Street streetcar line in Los Angeles. The dispute began on April 24 when the workers, known as the "Traqueros", demanded higher wages to match those of the European immigrants working on the same project, and stopped work. It ended on April 29 when the union organising the strike failed to persuade workers on rest of the streetcar system to join the strike, and the labourers returned to work.
