Treinposities - Spooragenda

Having just shared the Eisenbahn-Planer, I have to post about the Treinposities rail agenda. This is a curated list of rail events in the Netherlands that gets updated regularly by the site administrators. The site has many more interesting pages, with details on rolling stock in the Netherlands and other countries, live map of trains in the Netherlands, details on train routes with expected rolling stock, and much more.
