	Also, 15s had extension springs on track brakes  --  17-city cars
always had compression springs.

Assignment__For__FWS3:::::::

	Next time at PTM, please check the spare PCC trucks.    B2Bs have an
obvious cradle welded to the tube frame for holding the 
Rubber--Spring  bolster.    **-PCC The Car That Fought Back-**  
pg.128 shows 3-photos of the  *Demonstration__B2B*   ---   with clear
photo of cradle.    If there are any spares with the WAB drum
actuator, a check of the bolster mount will be revealing.

	In addition to PRCo and TTC not utilizing Super-Resilient wheels and
GE-Actuators, PRCo did Not have Extension springs on the track brake.
