More than 100,000 miners, railway workers and London bus drivers staged a one-day strike yesterday, creating chaos for British travelers on the worst day of industrial unrest for years.
   The first strike in the railway industry for four years, in protest of proposed job cuts, is expected to halt the whole network on the busiest day of the week for train travel. The bus strike will worsen Londoners’ misery. Bus drivers are protesting against new job practices and pay cuts as the bus system prepares for privatization.
   Police forecast chaos on the roads ms commuters attempt to get to work by car. Hundreds of thousands of people are expected to stay at home to avoid the crush, likely to be made worse by bad weather. About 2 million people travel into London every day and most of them use public transport.
   Miners’ leaders hope 10,000 people will join a march through the Yorkshire coal town of Barnsley to protest at government-imposed pit closures which will cost 15,000 miners their jobs.
   Prime Minister John Major called the railway workers’ action "deplorable" on Thursday. But union leaders say they believe the public, concerned at the inexorable rise in unemployment after two years of recession, understand their action.
