¨¨¨¨¨¨^~^† 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. @£@†^~^¨¨¨

¨¨^~^†@£@# wheels of the  train and the rail metal, #@£@†^~^¨¨
¨¨¨^~^†@£@ there are limits  for how  acute a curve @£@†^~^¨¨¨

¨¨¨¨¨^~^†@ the  ground  under  the  rails   can  be @†^~^¨¨¨¨¨

¨¨¨¨¨¨¨^~^ on top of hills, rather through them  in ^~^¨¨¨¨¨¨¨
¨¨¨¨¨¨¨¨^~ tunnels   (if  they   are   large),   or ~^¨¨¨¨¨¨¨¨
