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!
