Please answer the following question: Information: - Swiss Federal Railways is the national railway company of Switzerland. It is usually referred to by the initials of its German, French and Italian names, either concatenated as SBBCFFFFS, or used separately. The Romansh version of its name, "Viafiers federalas svizras", is not officially used. - Ferrovie dello Stato Italiane S.p.A. (previously Ferrovie dello Stato, FS) (in English "Italian State Railways") is a government-owned holding company that manages infrastructure and services on the Italian rail network. One of the subsidiaries of the company, Trenitalia, is the main rail operator in Italy. - Trenitalia is the primary train operator in Italy. Trenitalia is owned by Ferrovie dello Stato Italiane, itself owned by the Italian Government. It was created in the year 2000 following the EU directive on the deregulation of rail transport even if the company privatisation was only formal as the Italian government ultimately retains a 100% interest. - A railway company or railroad company is an entity that operates a railroad track or trains. Such a company can either be private or public. Some railway companies operate both the trains and the track, while particularly in European Union ownership of track and train operation is separated in different companies. - A train is a form of rail transport consisting of a series of vehicles that usually runs along a rail track to transport cargo or passengers. Motive power is provided by a separate locomotive or individual motors in self-propelled multiple units. Although historically steam propulsion dominated, the most common modern forms are diesel and electric locomotives, the latter supplied by overhead wires or additional rails. Other energy sources include horses, engine or water-driven rope or wire winch, gravity, pneumatics, batteries, and gas turbines. Train tracks usually consist of two running rails, sometimes supplemented by additional rails such as electric conducting rails and rack rails, with a limited number of monorails and maglev guideways in the mix. The word 'train' comes from the Old French "trahiner", from the Latin "trahere" 'pull, draw'. - Rail transport is a means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks. It is also commonly referred to as train transport. In contrast to road transport, where vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on ties (sleepers) and ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface. - Cisalpino AG was a railway company , referred to as CIS in timetables , operating international trains between Switzerland and Italy connecting Basel , Schaffhausen , Zurich , Geneva , Milan , Venice , Trieste , Livorno , and Florence . The company has its legal headquarters in Muri bei Bern , Switzerland , and is jointly owned by the Swiss Federal Railways and Trenitalia . It was founded in 1993 to operate fast trains across the Alps using tilting trains . In 2005 , however , it also took over all daytime long - distance passenger trains between Switzerland and Italy run with conventional , non-tilting trains . In the fall of 2009 , the project was abandoned because of mounting bad press over the quality of service and the fiasco surrounding orders placed for new trains . The remaining trains were split nearly evenly between the two owners . Till December 2012 the company owned the ETR 610 trainsets and leased them to Trenitalia and the Swiss Federal Railways ( SBB CFF FFS ) . The company still exists , but its name is no longer used for public purposes . What is the relationship between 'cisalpino' and 'limited'?
