| Rail | |
| "Though the same shape as the old fashioned T-Rail, it is hollow, and is claimed to be of better texture-- "anti-laminating," or less liable to "scale off" than the old iron. Besides this, it is a savings of 20 tons per mile -- the hollow rail requiring only 80 tons to the mile, while the solid requires 100 tons." Clarksville Chronicle of May, 1859. | |
