Fahrplan.app permits easy Internet inquiries about regional public transportation connections in the German Rhein-Main area around Frankfurt, without the help of a Web browser, and with the possibility of storing often used connections as shortcuts. Printing single or collected answers is easily possible.
Since the Rhein-Main specific decoding is done in a Perl script, adaptation to other regional public transportation systems (at least in Germany) should be possible for those with a knowledge of Perl.
On the upper left of the window, you enter your query. A click on the Suchen (Search) button will submit the query to the appropriate Internet server, and the results will be displayed in the lower part of the window.
A click on the button reverses start and destination, thus permitting a fast inquiry upon possible return trips.
A click on the button stores the entered data under a personal name; it can be recalled from then on by a single mouse click on the pop-up list below.
