1.   There are errors in the PERC map.  Ed found some; I don't know  
if he found all.

2.   An all-time map can represent only a "point in time" whereas  
track configurations to change over time.   For example, companies  
also commonly adjusted siding locations to variations in running  
times as vehicle loads changed through the years.   A railway might  
have been nice enough to give you a clue by renaming Siding A to  
Siding B or you may just accidentally discover that the distance  
between C and D changed from 3200 feet to 2800 feet while that from D  
to E changed from 2900 feet to 3300 feet.   Another example ... there  
used to be a trailing crossover on Perrysville Avenue north of East  
Street where route 8 cars reversed.   This was no longer needed after  
Keating Car House opened and the 8 line was extended farther north.    
It may or may not show on the map, if it does or does not it will be  
wrong for some point in time.   (Unless, of course, it was never  
removed.)

(I may have used a very bad example with the route 8 crossover.   My  
mother had a girl friend in Perry High School who came in from  
Warrendale on the PHB&NC interurban back in the days when rural  
school children received high school diplomas in city schools.   My  
mother said something about her coming in on a school car ... could  
be true or could be faulty memory.   If true, might have used the  
crossover or might have gone to Keating.)

There is a track book in the library that you may wish to look  
through when you come to Pittsburgh next spring.....
