The "Who invented the steam engine?"[0] section of "The Book of General Ignorance" refers to a "brilliant essay" by Arnold Toynbee that imagines a global Greek empire enabled by a rail network derived from combining the aeolopile and the Diolkos. I'd love to read that essay but they don't cite it and I have yet to come across it myself.
