There is the airport bus, the underground, or the train to Paddington (http://www.heathrowexpress.co.uk/ ); I definately favor the latter, as it is a quick, comfortable ride and you connect easily to the underground. As far as London to Bishops Stortford, check out the Railtrack web site at http://www.railtrack.co.uk/travel/ . These and a lot more are on the UK Public Transportation Information site at http://www.pti.org.uk/
