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!
