#¶#**†=^,, 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. ,,,^=†**#¶
#**†=^,,,,                                          ,,,,^=†**#

*†=^,,,,,, 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 ,,,,^=†**#

##¶#**†=^, 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 ,,,,^=†**#

*†=^,,,,,, to be interpreted  by the train drivers. ,,,,,,^=†*
**†=^,,,,, different  parts  of  the  railway  have ,,,,,^=†**

#¶#**†=^,, sometimes, trains have to stop and  wait ,,^=†**#¶#
##¶#**†=^, for something  to happen, far away. this ,^=†**#¶##
#¶#**†=^,, is  signaled  by  red  or green  lights. ,,^=†**#¶#
