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!
