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!
