The QGIS Trajectools plugin provides a collection of tools for handling movement data, including trajectories and public transport data in GTFS format. 

The Trajectools algorithms are integrated in the QGIS Processing toolbox:

Trajectory Data

Algorithms that create trajectories, provide both line and point-based outputs and the resulting layers are styled to facilitate interpretation:

GTFS Data

Of course, not all algorithms create trajectories. For example, the GTFS Extract segments algorithms, which creates a line layer of public transport network segments:

Trajectools is under active development and there are some exciting features coming up. If you’d like to contribute to this project, you’re welcome to head on over to the Github repo!
