¨--*^%£### 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. ##%^^--¨¨¨
