¨,~^$%@#@# trains are so constructed that they #@#@%$^~,¨
¨,~^$%@@## have to follow a set path. this path is ##@@%$^~,¨
¨¨¨¨¨¨,^%# 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. @@%^^,,¨¨¨
¨¨¨¨¨¨~$%# #%$~¨¨¨¨¨¨
¨,~^$%@#@@ sometimes, trains have to stop and wait @@#@%$^~,¨
¨,~^$%%%%# for something to happen, far away. this #%%%%$^~,¨
¨,~^$%@#@@ is signaled by red or green lights. @@#@%$^~,¨
