vertical stroke being the north-south tracks and the top bar the
east-west tracks which are down one floor.

line a fair bit easier.
Yes there are some techniques for making mental maps, but I don't
know how to explain them.  Presumably o and M people do a they
earn theri living teaching people how to get around.
Good luck.
