###££§†~^, ,^~†§££###
###££§†~^, 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! ,^~†§££###
