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!
