That’s the el in the Chicago Loop, looking photogenic, as it always does. There’s no great difference between the el and the elevated portions of the NYC subway, particularly since some of the elevated subways were built as els before the subways were built and later repurposed.
But styles vary among engineers, and the NYC elevated structures tend more towards plate girders than the elegant trussed girders seen here. It looks familiar, but it’s not quite right to be home.
