The latest update for Google Search, already available in Google Play for all to download, brings new bus and train cards for users, as well as an updated card for users of Google Now’s flight reminders.
After updating, if you utilize Google Now’s ability to pull existing flight data into your feed, Google will notify you of flight alternatives, should your scheduled flight be delayed for whatever reason.
In addition, Google Now will also pull existing Train and Bus reservations from your Gmail, creating cards for those occasions and placing them into your feed.
On top of it all, Google states they have added in a few bug fixes and performance improvements.
Go grab the update.
