###¤¤*/~^, 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 ,^~/*¤¤###
