[PRCo] West Penn 706 Question

[Fredbruhn at aol.com]

West Penn 706 was the regularly scheduled car on the Fairchance line.  Almost 
all of the photos I have show this car, or an 831 series holding down the 
schedule.
Car 706 and its sister 705 are shown to have 58 seats after being rebuilt in 
the 1930's  
while the balance of 707-739 show 54 seats.  

My question is, can anyone tell me why 706 was used mostly (if not entirely) 
on the Fairchance line, and where did the extra space come from for the 4 
additional seats.
Would eliminating the restroom provide that much space?

If 706 lacked lavatory facilities and the Fairchance line was the shortest 
served by the 700 series, maybe management felt patrons could hold their needs 
for the length of the trip.  

Thanks for any help, factual or otherwise.
