I found this to be a rather interesting photo during the challenge, brought a smile to my face with the title.
I think the idea you have going here is cute and would have done fantastic had this been an abstract challenge. After reading the comments I believe you were like me, you did a still life and yet those who couldn't think past a traditional studio still shot didn't understand the still life here. Only thing I would change in this is the placement of connectors or whatever you call them in the center. With the strength of the lines to the right I would have cropped out the bottom to the left and brought the connectors to the bottom left third to create more of a sunburst effect with the different lines.
Very nice thinking outside of the traditional still life!
lol. funny thought, but i guess even trolley's need a little lovin' sometimes, too. stretching the definition of still life a litte, perhaps, but i'll let it slide. interesting composition with all the sectioning of negative space...
