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!
