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!
