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!
