Why do subway trains skip stops?
Trains on the same track cannot pass each other like buses can, and so to increase speed, changes can only be made in terms of headway, or in which stations are served. Skipping stations increases the average speed of trains, thus making journeys quicker and more appealing to commuters.
Why is the Tube so far underground?
Building underground railways so close to the surface proved to be a very expensive exercise and it was realised that considerable costs would be saved if new tubes could be built at a deeper level, where they would involve much less disruption to existing buildings and services.
