PCC 1700 Crosstown Route

[ray]

Hello. I just finally purchased PCC Coast to Coast. This book states that
1700 ran on the 22 Crosstown line for a couple of months. Is this true, and
if so does anyone know why? I also noticed that the car did not have the
metal "cow catcher" pilot. The Pittsburgh trolley Pictorial shows  1700
with the metal pilot. I thought these cars came this way from St. Louis.
Did PRCo add the pilot and roof light?

Thanks  Ray
