In 1887 Philadelphia held a parade to celebrate the Centennial of the US Constitution. One of the larger corporate citizens, Baldwin Locomotive Works, put on a great show. On a dozen horse-drawn wagons, finished locomotive components from wheels to cabs and cylinders were displayed but the climax was an entire narrow gauge locomotive on a wagon pulled by 32 horses. With steam up, the engine's drivers revolved slowly on rollers. Must have been quite a spectacle moving through the streets.
