Route 5: Vestli - Sognsvann
The northeastern part of Route 4 («Grorudbanen», the Grorud line) is also served by the eastern part of route 5. This route has a loop, and passes the city centre core section of the metro network twice (as shown on the metro map on in the «Oslo 1» article. Let us have a look at that one.Which Direction?
I have started route 1 in the east (Bergkrystallen), and route 4 followed on. The problem now is that route 4 changes direction as it passes the city centre on its way to Vestli, whereas route 5 should start there. This makes it hard to just copy the route definition file for route 4. But we can use the helper program «reverse-route-simple» to reverse a route definition file.
$ ./reverse-route-simple oslo-metro/04.def
This program will print the route definition file, reversed. Here is the first 8 rows:
OS450 A B:4 Vestli
OS449 A B Stovner
OS448 A B:2 Rommen
OS447 A B Romsås
OS446 A B Grorud
OS445 A:2 B Ammerud
OS444 A B Kalbakken
OS443 A B:3 Rødtvet
…
Note the missing comment at the top, and the lack of tabulation (as the columns was nicely placed in the original file).
I have written a modified version of the program fixing both issues, called «reverse-route».
$ ./reverse-route oslo-metro/04.def
The output looks much nicer now:
#
# Vestli - Bergkrystallen
# ------------------------------
OS450 A B:4 Vestli
OS449 A B Stovner
OS448 A B:2 Rommen
OS447 A B Romsås
OS446 A B Grorud
…
Route 5 has a loop, as I have told already, running through the city centre section twice on its way from Vestli to Sognsvann. This program supports multiple visits to the same stop or stops on a route, but they will all be reported with the final destination (in the timingpoint part). It is also difficult (impossible) to set up short runnings with stops that are visited twice, as it will choose on of them. Which one is an implementation detail, and can change in the future.
I have therefore chosen to split route in two, at the middle point «Storo». This gives route 5A Vestli - Tøyen - Stortinget - Storo, and route 5B Storo - Tøyen - Stortinget - Sognsvann. They are combined at Storo.
Note that Tøyen has three platforms, with route 5 (5A and 5B) using plattform C towards the city centre:
The route 5A definition looks like this:

The routes are set up with zero minutes between arrival and departure at Storo. This required some trial and error.
