In 1862 the railway stations in Černošice were opened as a part of the new-built railway from Prague to Plzeň. The new railway brought about a tourist and building boom. Lidos were founded along the river and many new villas were built. Černošice became one of the most famous residential and weekend-cottage satellites before. During this time Černošice started to lose its agricultural character. The development of the towns was stopped during the World Wars. In 1950, the originally separate villages were joined together and named Černošice.
