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!
