Assume that regional trains are slower, taking 45 minutes to
traverse this track if there are no capacity constraints, while long-
distance need only 25 min. In the current situation, there are
3 regional trains per hour with a total of 1000 passengers, and 3
long-distance trains per hour, also with 1000 passengers. The
longest track segment on the 100 km single track line segment
between two stations is 15 km. The other parameters are
unchanged from the example with a single train type.
Now, the regional train operator wants to increase capacity by
increasing the number of meeting stations such that the longest
track segment decreases from 15 km to 3 km, and extend the
timetable to 6 trains/hour. Given 6 regional trains/h, the long-
distance operator would maximize profits by running 5 trains/h in
the new situation. The first row of Table 5 shows the benefits of
the investment with the timetables that will be the actual out-
come in the do-nothing and the investment scenarios: 87 kSEK/h.
