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!
