 **A client for HAFAS public transport APIs**. Sort of like [public-transport-enable](https://github.com/schildbach/public-transport-enabler), but with a smaller scope. It also contains customisations for the following transport networks:
 
 - [Deutsche Bahn](https://en.wikipedia.org/wiki/Deutsche_Bahn) – [src](p/db/index.js)
+- [Berlin public transport](https://en.wikipedia.org/wiki/Verkehrsverbund_Berlin-Brandenburg) – [src](p/vbb/index.js)
