Once the planners had settled on a rough map of where trains should go, it was up to the civil engineers to determine exact alignments, both horizontally (plan) and vertically (profile). From the beginning, engineers drafted rough plans, to get a sense of how much the system would cost. As the project progressed, they worked with architects to draft directive drawings for prototypical sections. For the underground portions, engineers conducted more than a thousand test borings, while for the above ground portions they planned aerial bridges as well. | |||||||||||||||||||
