Anyone know what it is?

That's the low bridge warning sound. If a bus is within a certain radius of a low bridge, there will be a warning sound of some sort (there's various types depending on the bus - some beep, some shout 'WARNING', etc).

This serves as an alert to the driver, and makes them aware of the potential hazard.
