Other public transportation apps are spying on you and selling your location data! πŸ•΅
Our philosophy is simple: Tracking your bus or train is not consent for you to be tracked. Your journey should be private.
We do not sell your location data, in fact, we don't even collect or save it!

Headed back to school? 🏫 Try transit! Many agencies offer "school-oriented routes" that are dedicated to students. Anyone can ride these buses, but they usually only run before and after school. Other agencies offer "trippers" that provide extra service. Whatever your commute is, good luck!

Jul 30, 1953: the TTC's first two subway cars arrive in Toronto after overseas shipment from Gloucester, England. The cars had arrived by ship in Montreal the day before and were loaded onto railway flat cars for transport to Toronto. 1/2

So, who likes driving to LAX? Really? No one? Good news! Catenary has live locations for LAX shuttle buses, including the [M] Metro Connector shuttle to the new LAX/Metro Transit Center!

For example, most of the USA and Canada, most of France, Poland, Czhecia, Australia, England, Ireland, Australia, Japan, etc etc.

We reckon only a small percentage of users are interested in this.

Thank you for the clarification. The problem is we have an extreme amount of data from thousands of agencies across multiple continents. We are still evaluating the storage requirements of storing this much data for a small use case, and if it is worth it to us.

This is not related to their own delay calculation, it's based on calendar estimation system that we are almost finished with. We need to basically guess the starting service date of the trip in the correct timezone, and this is important especially around midnight.

The delay field needs to show up for MTS, but the delay algorithm hasn't been finished yet. It'll be fixed tonight.

Transit adventures? Transit adventures! 🚌 ✨

Take MTS route 84 to the Cabrillo National Monument stop, right inside the park gate, to explore the old Point Loma lighthouse and get beautiful views of the San Diego Bay and the ocean. And...of course...track your bus on Catenary!

There is a seperator to combine fields of data. This is why.

Brand new feature!
Click the purple pin button to find departures from that point. Click the centre button to move the marker to the centre of the screen.

The map pin is also draggable!

P.S. nearby departures algorithm is now much faster!!!
