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!
