Heathrow Express (aka HEX)
 

A quick reminder to everyone that it's possible to purchase deeply discounted (5 quid!) tickets on the HEX to/from Paddington. The tickets are valid on any train for the date purchased and must be purchased in advance on their website (www.heathrowexpress.com). For groups traveling together, a car hire or car service may be an option but for 1 or 2 people traveling, this is a bargain!
