RAILS                   
                                          
                                          
  
                                          
  
                                          
                                          
 TRAINS  ARE  SO  CONSTRUCTED  THAT  THEY 
 HAVE TO FOLLOW  A SET PATH. THIS PATH IS 
 CALLED  A "RAILWAY", WHICH  IS COMPRISED 
 OF  TWO METAL RAILS, HENCE ITS NICKNAME. 
                                          
 BECAUSE  THE LOW  FRICTION  BETWEEN  THE 
 WHEELS OF  THE TRAIN AND THE RAIL METAL, 
 THERE ARE LIMITS  FOR HOW  ACUTE A CURVE 
 CAN BE, AND EVEN  MORE SO  FOR HOW  MUCH 
 THE  GROUND  UNDER  THE  RAILS   CAN  BE 
 SLOPED. THUS  A RAILWAY IS OFTEN NOT LED 
 ON TOP OF HILLS, RATHER THROUGH THEM  IN 
 TUNNELS  (IF   THEY   ARE   LARGE),   OR 
            ARTIFICIAL CHASMS.            
                                          
 THERE WILL BE TREES ON THE  SIDE  OF THE 
 RAILS, BUT NOT TOO CLOSE, OR  THEY  WILL 
 BE CUT  DOWN  BY  THE RAILWAY  JANITORS. 
 THERE  WILL  BE  PLAINS,  AND  BODIES OF 
                  WATER.                  
                                          
 TRAINS  GO BY  DAY AND BY  NIGHT.  ALONG 
       THE WAY, THERE IS INFORMATION      
 SCATTERED, OFTEN PUT  ON  TOP  OF POLES, 
 TO BE  INTERPRETED BY THE TRAIN DRIVERS. 
 DIFFERENT  PARTS  OF  THE  RAILWAY  HAVE 
          DIFFERENT SPEED LIMITS.         
                                          
 SOMETIMES,  TRAINS HAVE TO STOP AND WAIT 
 FOR  SOMETHING TO HAPPEN, FAR AWAY. THIS 
 IS  SIGNALED BY  RED  OR  GREEN  LIGHTS. 
                                          
                                  
                                          
 MANY PEOPLE FOLLOW  THE  RAILS BY  FOOT. 
 OFTEN  THIS  PROVES  TO BE  THE  SHORTER 
 PATH  BETWEEN  TWO POINTS. HOWEVER  THIS 
 IS  FROWNED  UPON,  AND  VERY   IMPOLITE 
        TOWARD THE TRAIN DRIVERS!
