[PRCo] Route 51 Bon Air

[Mark McGuire]

  My appologies if this has been discussed before. Where was the end
of rt. 51 located? I know the double-enders had to change ends at
the end of the line on McKinley. Where was the other end located? 
Carrick CH? Suburban CH? Or did the cars just change ends again at
McKinley and Brownsville?
