OMGs! Freakiest Train Dream EVER!

I dreamed I was at an intersection and there was a train stopped on the railroad track just to the side of the road.  As it was blocking the tracks the railway system started running the trains on the road.  So in front of me on the other side of the track are two trains sitting side by side waiting for the cross traffic, also trains, to clear so they could cross.  I was in a small red car, and behind me were two trains side by side waiting for the cross traffic, the trains on the road, to clear.  I was terrified of driving in front of trains so I pulled my car over and parked until the melee could be cleared and the trains were back on the track.  I walked around for something to do to kill time and found a place that sold gravel and stone goods, and when I went in a woman and man started making a fuss over me wanting to order me some gravel, I think I was allowing them to.  The man, an old man was saying the gravel was broken by prisoners, and the gravel would come from a prison.  I had entered the building on some stone steps with designs painted on their fronts, that was really pretty and a good idea, I thought.

The trains were long with many cars and all the engines were black with white markings on the front and "chiseled" in design.  The fronts were angled rather than round.  The time of day I'm assuming was late afternoon going to nightfall and it was foggy.  That was the weirdest thing EVER.
