Train paralleling Holland Avenue, the main thoroughfare, with horn blowing loudly and persistently as it transits the city.
This happens multiple times day and night, 24/7. Unfortunately this photo was taken from our Holland Hotel room's window next to our bed!

The Hotel Ritchey is the white building just above the train's leading engine, to the left of this photo about half way from the top edge.
