,,~-^*%£## trains  are  so  constructed  that  they ##£%*^-~,,
,~-^*%£### have to  follow a set path. this path is ###£%*^-~,
,,~-^*%£## called  a "railway", which is  comprised ##£%*^-~,,

,,~-^*%£##                                          ##£%*^-~,,
,~-^*%£### 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 ##£%*^-~,,

,,~-^*%£##                                          ##£%*^-~,,

,,~-^*%£## rails, but not too  close,  or they will ##£%*^-~,,
,~-^*%£### be  cut  down  by  the railway janitors. ###£%*^-~,
,,~-^*%£## there will  be  plains,  and  bodies  of ##£%*^-~,,

,~-^*%£### 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. ##£%*^-~,,

,~-^*%£### is  frowned  upon,  and   very  impolite ###£%*^-~,
