Whilst on the Piccadilly line today, the train stopped for a long period. Finally a voice crackled.
" Problem at Holborn - will keep you advised". About ten minutes later:
" Ladees end Gennelmen - Oim delighted to siy the problem has been sawted. This train will shortly depart. " Pause." It will shortly depart for all stations all the way ." Pause" All the way to er, wherever"
And I thought the tubes only went along one line.
