Lima Metro: Line 2 And Line 3 Will Be Built Underground

Both Line 2 and Line 3 of the Peruvian capital will be constructed underground, as they will be serving densely populated and heavily urbanised parts of the city, according to the country’s Minister of Transport and Communications Jose Gallardo.

“Lima’s Line 3 has to be underground because the success of a train is to go through areas where the maximum demand is located,” he told.

Line 3 of the cities metro network is projected to transport the highest number of passengers per day.

“We will witness a great leap in the number of Metro system users in Lima. We will go from 300,000 users thank to Line 1, to 1 million passengers with Line 2, and afterwards to 2 million passengers with Line 3,” he told TV Peru official station.

Other South American cities have found challenges with both overground and subterranean metro networks in heavily urbanised and established cities.

An overground monorail solution was developed in Sao Paulo in recent years, as many of the cities older skyscrapers had very deep foundations, meaning a subterranean solution would need to be constructed at a great depth or the route would need to avoid some of the most urbanised.

The Bogota Metro project faced simular challenges, with engineering studies uncovering that the route that was first earmarked would result in the collapse of a number of the cities taller buildings. As with Lima, it was decided that the additional time, cost and engineering challenges resulting from developing an underground network, were worth facing, as subterranean metro provides increased capacity and connects areas of greatest demand.
