Hi Guys! I have a good question .I hope someone might shed some light on it for me,Today i was Delivering A big Pasta order 30 miles away from my store for a wedding ,Now the track is all along the way on Casa Grande HWY In AZ. Between Maricopa And Casa Grande And Long Behold In the Middle Of Nowhere A AutoRack Filled with Cars All by itself, I was Thinking it became Uncoupled and rolled to a stop,What do you think? Nothing Else was around at all just the road and 1 main line track.

Find yourself a ramp and enjoy your new car 
It is probably a bad order setout. Other, not so serious, suggestions are that it is being used as a conversation piece or it has been bad and is being punished (sounds like the first idea, except for the reason).
I bet if you hung around you might have seen a crew working on it. Funny they would leave it on the main line though.
I’ve seen full auto racks in that area several times. They are on a siding, not the main line. My speculation is that it is where cars are unloaded for trucking to Phoenix and Tucson.
Maybe a maintanance problem. Are you sure that track was a main? They let cars sit on the “main” by me all the time if there is no other traffic.
If the coupler jaw had opened or any coupler part had broken so that the car dropped off the back of the train the air pipe for the brake would also have ripped out and the whole train would have gone into “emergency” stopping the whole train:- fast.
Also a last car would have a FRED on it.
If it got left behind without either of these the crew would be fired for dangerous working - because the brake should be working right through the train exactly to stop a car being lost and the FRED is there to prove that ALL of the train is there.
It seems very trusting thee days to just par an autorack full of cars. there’s places near me where they’s steal the autorack - as well. [|(]
Phoenix has its own vehicle terminal.

It seems like vehicles destined for Tucson would be unloaded at Phoenix. It appears that the Kidron plant in Tulare, CA. unloads cab/chassis assemblies from autocarriers at SJVR’s yard in Exeter, CA. Perhaps if these is some plant in the area similar to Kidron, they may unload cars in the middle of nowhere, but it seems odd otherwise.
You know it might have been a siding,But, Im telling you for sure there was nothing in a sqaure 5 mile area, there was nothing ,just striked me as a weired thing ive never seen

Well, if it had come uncoupled, it definately would have dumped the air.
