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!
