I just added analysis support for OSM’s public-transport to ptna for
- BR-CE-Metrofor
- Companhia Cearense de Transportes Metropolitanos (Metrofor)
- Municípios de Fortaleza, Caucaia e Maracanaú / Ceará
- CSV input data Metrofor Linhas in OSM wiki has not yet been prepared
- gtfs might follow, checking the license
