Praise

All lines can be used with the Oyster card used across London. The London Overground has received praise for its transformation of long-neglected lines into clean and reliable services, with passenger usage increasing sharply such that the British Rail Class 378 trains had to be extended from 3 cars in 2007 to 5 cars in 2015.^[2] In the autumn 2011 National Passenger Survey, London Overground received an overall satisfaction rating of 92%, a 7% improvement on the previous survey.^[3]
