Some London train drivers get paid more than pilots. The highest-paid drivers on London's Underground got $130,000 last year. The basic salary is $70,000 a year. This is twice the salary of a nurse. London's police officers start at $28,000. London Underground train drivers also get eight weeks holiday a year.

Many people think the salaries are unfair because the job of a train driver is getting easier. Many drivers no longer have to drive trains. On automated trains, they only have to open and close the doors. A spokesman said their pay was for "professionalism". Thousands of passengers travel on the London Underground every day.
