An RPO catching the mail sack

For several years I've had a static display of a boiler room project of a mail crane and a couple RPO's with catcher arms. I decided that an operating
system would be something to try out. I modified the mail sack so it would come loose from the crane without derailing the car. See my staged photo of this nonsense at, http://www.rrscenery.com
