The group met in the parking lot. It was a pretty good turnout, which is not surprising given the type of event.
First stop on the tour was the axle press that separates or joins various axle components including wheels, bearings and gearboxes.
Next stop was the machine shoppe area with the typical slate of drill presses, lathes and band saws.
PATCO's wheel truing machine is an older style that requires the trucks to removed and placed onto the machine with a crane. Newer wheel machines can work on trucks that are still under the vehicle. The machine grinds down worn wheels to restore the profile and remove flat spots.
Speaking of trucks, PATCO is one of two remaining users of the Pioneer III truck, the other being Amtrak with the Amfleet series. The P-III was designed by the Budd company as a lightweight truck that would derail less on bad track. It was available in both powered and unpowered variants and was previously installed on the SEPTA Silverliner II and MTA M1s.
The truck frames some in two halves and as you can see they are very simple affairs.
These gearboxes are connected to the truck and transmit power from the motors to the axles.
Here we see spare axle and gearbox assemblies ready to be connected to a truck.
PATCO uses GE 1255 A3 motors rated for 140 HP at 650/325 volts DC and 4600 RPM.
Two motors are mounted on each truck for a total of 560hp/car.
Finally the truck is mated to the car via this bolster, which I think uses an air bag suspension system and creates the soft bouncy ride.
