   Thanks for the pictures.    I'm always interested in mechanical details.

    On the first photo, you mentioned that the rear of the motor faces the bolster.    Is this the practice on two axle trucks?    I seem to remember reading some years ago that three-axle trucks had switched to having all motors facing the same way to make the tractive force of each one more equal or something like that.     Am I right or wrong on either of these statements?

First photo is the inside or rear of the motor, this faces inward towards the center bolster.

The two ears or studs hold the traction motor against a stop, which keeps it from spinning on the axle.

Look at them, come up with questions and comments.
