Blue Double Decker Bus​ (LEGO Alternative Bricks)

A double-decker bus is a vehicle with two levels, or decks, designed to transport a large number of passengers efficiently. This design maximizes passenger capacity without requiring additional road space, making it particularly effective in densely populated urban areas. The upper deck offers passengers elevated views of the surroundings, enhancing the travel experience, especially for tourists. Modern double-decker buses are equipped with amenities such as air conditioning, Wi-Fi, and accessibility features to accommodate all passengers.​

Historically, double-decker buses have been iconic in cities like London, where the AEC Routemaster became a symbol of British public transport. Introduced in the 1950s, the Routemaster featured an open rear platform and operated in London until 2005. Its successor, the New Routemaster, was introduced in 2012, offering modern features while retaining the classic design elements. Today, double-decker buses are used worldwide, not only for regular public transportation but also for sightseeing tours, providing panoramic views of cityscapes and landmarks.
