ondon’s famed Tube is known for being one of the most efficient, extensive and clean transit systems in the world. But aside from that, it’s also one that is plagued with more than its fair share of drunken riots and boisterous individuals who are known to cause the odd problem or two. Now, following suit of other cities around the world, the Tube is drying up and meeting mixed reactions from London denizens.

As of June 1, it’s the last call for alcohol on the London transit system. Until now, the extremely extensive mode of transportation – which is responsible for shuttling around 3 million Londonders daily – has allowed open alcohol on all trains, subways and buses. The result is many i-bankers cracking open a can of beer on their commute home from the office. On weekends, things tend to be more aggressive, as club-bound twentysomethings turn metro trains into their very own pre-drinking spots.

The laissez faire attitude of London Town is being changed, as newly-elected Mayor Boris Johnson begins implementing some of his promised changes to the storied city. The former journalist-cum-politician used fighting crime as one of his strongest platforms in the recent election, and is now aiming to crack down and create a safer London. The alcohol ban is his first major decision, and the law will come into full effect only a mere 3 weeks after he announced it. Under the new rules, any passenger caught drinking alcohol will be asked to stop (tame) and be thrown off the transit system if they refuse. A new by-law, which is expected to be passed next year, would make drinking on the metro system a criminal offense, complete with a hefty fine.

Posters have already been put up to give passengers more than enough warning. The ban includes all subway services on the London Underground, all London buses, trams, and the Docklands Light Railway, which services the East End of London, including the Canary Wharf financial district. Many wonder, however, if the law will work out in the end.
