National Express are the UK's largest scheduled operator of long distance bus services. The network is truly national in England and Wales with most cities and towns of any consequence interconnected. In Scotland the network only covers the main cities but interconnects well with Scottish Citylink, the dominant Scottish operator.
In London, the National Express terminus is Victoria Coach Station, London's only major coach station. National Express also offer services that terminate or visit London's major airports, Heathrow, Gatwick, Stansted and Luton without going into London itself.
