Transport in Monaco is facilitated with road, air (helicopter), rail, and water networks.
Rail transport is operated by SNCF with only Monaco Monte Carlo station seeing passenger service and the total length of the line inside the Principality is 1.7 km (1.1 mi).
The railway is totally underground within Monegasque territory, and no trains can be seen at ground level within the nation.
The first, in 1964, was a 3,500 metre tunnel (mostly in French territory) which rendered the original Monte-Carlo station redundant.
Where the above ground railway was is now available for development, schools, hotels and commercial facilities, can locate here totaling some four hectares.
Due to the wealth of many visitors and residents, a significant portion of those flying into Nice for travel to Monaco take a helicopter flight to their final destination (see below).
