Apple Maps transit directions are expanding to Sweden, Norway, Denmark, and Finland. This is the biggest combined update so far.
Apple’s list of cities hasn’t been updated with Buffalo yet, so it appears that it will be gradually rolling out.
Apple Maps added support for transit directions in West Virginia this week, as first noted by AppleInsider. The directions included below are transit directions within the city of Charleston, WV. Support for this area isn’t listed on the Apple Maps feature list, yet, but they are live now. Our screenshot was taken early evening, Monday.
