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!
