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!
