Fig. 6i . Operation of Freight Car-Floats at a Railroad and Steamship Freight Terminal
Here we have time represented by days in the horizontal direction and by hours in the vertical direction. The object of the chart is to record whether car-floats are loaded and dispatched at the same hour each
Dotted lines show the time at which cars are pushed onto car-floats by locomotives. Solid line.s show the time at which car-floats are towed away by tug-boats. Curves for any one car-float destination are in pairs bearing the same letter.
