It's been some years since I've flown into Heathrow and was wondering if
there is a direct rail link right at the airport to head for the south
coast - my destination will be Weymouth in Dorset. Last time I was
there, we flew into Gatwick and caught the train right there but Air
Canada flies into Heathrow and that's the carrier I'm using for this
trip. Any info would be greatly appreciated.
