Paris builds four new metro lines, extending the network with 68 additional stations. See PTV, that’s how you build public transport infrastructure that has an impact. Unlike your “big build” to remove level crossings in the name of pedestrian safety. You don’t have to dig scores of station underground; a footbridge or subway with elevators for impaired humans will do the same. It would cost less and won’t disrupt trains for months. All it does is to remove obstacles for motorists so they don’t have to wait at boom barriers anymore. (via)
