Trip updates

Note: Trip updates API will be deprecated in the future in favor of Stop times GraphQL API. This is part of an effort to reduce overlapping API functionalities and to concentrate APIs under the GraphQL APIs.

Currently the service offers two GTFS-RT data feeds filled with trip updates, one for HSL data and one for FOLI (Turku) data.


Supported URL parameters

Parameter Type Description
operator path parameter id of an operator, either HSL or FOLI
