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!
