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!
