How are track sections counted for scoring, especially around towns and cities?

Question

Accepted Answer

One VP per section of track in a completed link, where sections are separated by tile edges and by cities and towns. A tile with a town counts each exit stub as its own section, so a straight tile with a town scores two. Bridge crossings don't split track, and the city hex itself scores nothing.
