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!
