T2 and Queens are both very poor and unattractive use of the limited space in Central Area and its demise is welcome. There is an opportunity now for a complete terminal ring. T3 and T2 have been within yards of each other for years and with the addition of the new A380 stands , even closer .They have been crying out for airside passenger link walkways and travellators. To the east the new T2/Queens should just be phase 1 of a combined T1 and T2. Carrying on round, the end of T1s Pier 4 A satellite is not far from the north eastern end of T3. There is the opportunity here for a first class development so, again,hopefully a new T2 will be seen as just the first stage of that.
Taking it all one step further, T 5 and T 3 should always have been designed as just 2 entrances to one terminal, with a full scale underground concourse including walkways and baggage conveyors between the tip of the outer T5 pier and the outer T3 pier which are within a very short distance of each other. The opportunity has been lost in the initial T5 project but could be recovered, albeit at higher cost than if it were incorporated in the first place.
