Revenue in its contracted London buses lifted 7%.Revenue in its rail division, which runs the Southern, Southeastern and London Midland rail franchises, rose between 7% and 9% while passenger journeys were up between 4.5% and 6%.It said in an update ahead of its annual meeting that trading in rail will remain challenging in the short term, but it was committed to UK rail.Chief Executive David Brown said: "Our bus division is performing well and we are on course to deliver our £100m target by 2015/16."In rail, our bid team is working hard to deliver strong bids for the Thameslink and Crossrail franchise competitions and we have begun discussions with the Department for Transport regarding the proposed extension for Southeastern."Overall, I am pleased with the group's performance and remain confident that the full year result will be in line with our expectations."PW
