Madrid Metro extension
For those who regularly endure the discomfort of London’s narrow, overcrowded Tube trains, a journey on the modern sections of the Madrid Metro will be just the tonic. Praised for its emphasis on functional, passenger-friendly design – with no unnecessary bells and whistles – the metro underwent a major extension programme in two phases between 1995 and 2003. Delivery of the extension in such a short timeframe was a major success that bucked the trend of cost and time overruns seen so frequently on subway construction projects. The use of a modular design and reliance on proven, pre-existing technology (no reinventing the wheel) were two key factors driving the high-speed, low-cost delivery of the extension programme.
