The arrival of 52m long trains on line one of the Lille Metro will allow trains to transfer to line two, resulting in a growth of 30% in transportation capacity. In order to store and maintain the additional trains, the garage-workshops will have to be expanded. At the terminus CH-Dron de Tourcoing (metro station), work is well on its way.
The expansion of line one will also benefit line two. In fact, each time a new 52m train goes into service on line one, Transpole will transfer a 26m train to line two. Eventually, 27 trains will join line two, increasing its fleet of 90 to 117 trains. This will allow growth of its travel frequency and increase its transportation capacity by 30%.
The more trains in use, the more trains to store and maintain. This is why the Métropole Européene de Lille (European Municipality of Lille) began the expansion of line two’s garages and workshops more than a year ago. Beyond the terminus CH-Dron, in Tourcoing, work is already well on its way. A building around 200m long by 20m wide was erected: the new garage. It will house four tracks, each capable of holding six trains. It will increase the capacity of the Dron Garage from thrity to fifty-four 26m trains.
From the exterior, this industrial building resembles the original garage to which it is attached like a brother. Its design and the contemporary materials, however, will improve its ventilation and natural lighting. Inside, the exposed beams of light wood gives this vast, empty hanger the feel of a sporting hall.
Along with the architectural novelties is an innovation that totally escapes the notice of visitors. A cistern of 45m3 is buried on the side of the building. It receives rainwater collected by the joint gutter of the two buildings (old and new), from around 9,000m2 of roof area. This cistern provides the filtered water needed to wash the metro trains: an economical and ecological solution.
Does your city also engage in green innovation in its public works? Should a city aim to find architectural solutions that are both economical and ecological, or should they focus more on one than the other? Share your city's stories and your thoughts in the comments area below.
