Leave it to the Dutch to update a rail station to focus on bicycles.
At the Central Railway Station of Delft (Netherlands) there is room to park 5,000 bicycles in an underground bicycle parking facility.
More information in this blog post. As the video shows, the station features seamless entry from the local bike path, two-tier parking (loading a bike onto the top rack is not as tricky as some people make it), electronic signboards that let you know how many free spaces are in each row, train-ticket sales machines, and video monitors that display train departure times. Revolving doors lead you directly into the station, and an escalator takes you down to the platform with commuter trains leaving for the Hague and Rotterdam. There’s even a bike-maintenance shop on the premises, and a bike-share station for those who don’t have their own rides. Upstairs, you’ll find the bus station, and outdoor parking for an additional 3,700 bikes.
