         12 . A rail vehicle for passenger transport, the rail vehicle comprising:
 at least one carriage, said carriage having an inner floor portion with a trough-shaped construction.   
     
     
         13 . The rail vehicle according to  claim 12 , wherein said trough-shaped inner floor portion is water-tight or coated in a water-tight manner. 
     
     
         14 . The rail vehicle according to  claim 12 , wherein said trough-shaped inner floor portion has edges formed with a circumferential profile and is otherwise constructed substantially planar. 
     
     
         15 . The rail vehicle according to  claim 12 , which further comprises water-carrying modules and collection troughs disposed on said inner floor and arranged below said water-carrying fitted modules. 
     
     
         16 . The rail vehicle according to  claim 15 , wherein said collection troughs are deep-drawn components produced from high-grade steel. 
     
     
         17 . The rail vehicle according to  claim 15 , wherein said collection troughs extend as far as a location behind said water-carrying fitted modules between said fitted modules and a wall of said carriage. 
     
     
         18 . The rail vehicle according to  claim 12 , wherein said trough-shaped inner floor portion is formed with liquid drains for conducting liquids away from an inner space of said carriage. 
     
     
         19 . The rail vehicle according to  claim 12 , wherein said trough-shaped inner floor portion is provided with a water-tight anti-slip layer in a region of a passage, said water-tight anti-slip layer having edges joined to surrounding components by way of a water-tight joining compound. 
     
     
         20 . The rail vehicle according to  claim 19 , wherein vertical gaps formed between fitted modules or collection troughs and adjoining the passage, are joined with said water-tight joining compound at a depth of at least 30 mm. 
     
     
         21 . The rail vehicle according to  claim 14 , wherein said circumferential profile comprises an angular strip having at least two members. 
     
     
         22 . The rail vehicle according to  claim 21 , wherein said angular strip is adhesively bonded to said otherwise substantially planar inner floor portion.
