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!
