Hong Kong KMB and LWB Bus Arrivals for a Route at a Stop

kmbeta/route-arrivals

Real-time arrival estimates for one KMB or LWB route at one Hong Kong bus stop: up to three next buses with expected arrival time, destination and remark, for both directions where the route calls at the stop. Arrival time is null when no bus is scheduled. A route that does not call at the stop returns an empty list.
