Safety Carrier for GE-58 Motor TO PREVENT damage to motors and derailing ofcars in case of the breaking of motor frame boltsand the consequent falling of the motor to the ground,the Denver (Col.) Tramway has placed safety carrierson all cars equipped with the GE-58 motor. The carrieris made complete from a few feet of i-in. iron rod is first bent double, the two ends are brought.

Several motors with broken bolts have beenfound suspended from the hooks at various times.
