Currently this library only implements a very small part of HAFAS and is very much not production ready. The library is built in such a way, that you can make requests using your own data structs if you want, but I'd recommend making a pull request and adding it to the library. Any help is welcome.

The Deutsche Bahn AG (abbreviated DB) is the German national railway company. As DB is one of the largest transport companies of the world and the largest railway operator in Europe (according to this source), a complex network of time schedules, trains and routes in Germany and other European countries has to be organized. To facilitate the online journey planner for customers the Software HAFAS (HaCon Fahrplan-Auskunfts-System) of the company HaCon (Hannover Consulting, belonging to Siemens) is used. Rust is a general-purpose programming language with outstanding performance and safety. It doesn’t require the use of a garbage collector or reference counting to ensure memory safety. Rust can be used for systems programming whilst also offering high-level features. For example, programs can be created with Rust to draw data from different software e.g. HAFAS.

The recommended way to access the documentation is through the generated HTML version in the docs folder. There is both rustdoc as mdbook documentation on this project, found in the docs folder.

The purpous of this project named HAFAS-RS, done for a high school presentation (GFS) by Adrian Struwe (Eskaan), was to develop a program to collect and list targeted data on trips, train types, locations and operators of the Deutsche Bahn.

It is currently licenced under the GPL3 licence, allowing open distribution and modification of the code. The project is fully documented, both in source code (per rustdoc) as in this mdbook.

The idea for this project is not my own. This has been done before by David Kriesel (using unkown methods) and was presented in the C36C3 Congress.

Credit also goes to Marudor and his bahn.expert project, it was very helpful for me to understand the inner workings of HAFAS¹.

The primary goal of the project was to extract data, e.g. the most used stations, and display them in a database.

Another goal was to query and compare train schedules to realtime data. Sadly, after many experiments I realized this API was designed to resist such data collection attempts.

In the future, I want try to find a feasible way (that does not overload the API) to collect such data.

I plan to continue my work on this project and maybe one day develop a good HAFAS library for Rust. This is the primary goal for the future, after which I plan to create a public API that serves better readable responses than HAFAS.

I am always happy to receive issues and pull requests on my projects, if this project catches on I will surely enjoy maintaining it.
