###£$†:«~¨ trains are so constructed that they ¨~«:†$£###
####£$†:~¨ have to follow a set path. this path is ¨~:†$£####
£†«¨¨¨¨¨¨¨ 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 ¨¨¨~~«†££#
###£$†:«~¨ the way, there is information ¨~«:†$£###
###£$†:«~¨ scattered, often put on top of poles, ¨~«:†$£###
###£$†:«~¨ to be interpreted by the train drivers. ¨~«:†$£###
£$†:~¨¨¨¨¨ different parts of the railway have ¨¨¨¨¨~:†$£
###£$†:«~¨ different speed limits. ¨~«:†$£###
#£†«~~¨¨¨¨ ¨¨¨¨~~«†£#
£$::~¨¨¨¨¨ sometimes, trains have to stop and wait ¨¨¨¨¨~::$£
###£$†:«~¨ for something to happen, far away. this ¨~«:†$£###
###£$†:«~¨ is signaled by red or green lights. ¨~«:†$£###

#£†«~~~¨¨¨ ¨¨¨~~~«†£#
###£$†:«~¨ many people follow the rails by foot. ¨~«:†$£###
###£$†:«~¨ often this proves to be the shorter ¨~«:†$£###
#£££$†:«~¨ path between two points. however this ¨~«:†$£££#
###£$†:«~¨ is frowned upon, and very impolite ¨~«:†$£###
####£$†:«¨ toward the train drivers! ¨«:†$£####
