How Do I Get By Train From Heathrow Airport To Middlesex?

Heath row airport is actually in Middlesex just outside of London (to the west). The airport does have it's own railway terminal but this would take you non-stop into the centre of London. If you only want to get to another part of Middlesex you would be better off using one of the bus/coach connections. Look at www.heathrowairport.com for detailed information on the airports public transport links.
