These ‘pinch point’ barriers at London’s Heathrow Airport prevent the baggage trolleys from the Bus Station being taken down the escalators which lead to Terminals 1, 2 and 3. Mistake-proofing (for safety reasons: a trolley down the escalator would be dangerous) but also unnecessary if the airport had been designed differently from the start. Is forcing users to load baggage on and off multiple trolleys whenever their path descends or ascends really desirable? A lift (elevator) may be available, but how many people – and their trolleys – can fit in it at once?
An inclined travelator (as used elsewhere at Heathrow) would be a better solution.
[...] Nevertheless, aside from the more obvious control elements of airport architecture – from baggage trolley width restrictors to the blind enforcement of arbitrary regulations, the retailers themselves are keen to make the most of this unique environment and the combination of excitement, stress, tiredness, and above all, confinement, which the passengers are undergoing: The new terminal may have been heralded as a “cathedral to flight”, but with 23,225 sq metres (250,000 sq ft) of retail space, the equivalent of six typical Asda stores, it is actually going to be a temple to retail.
