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!
