The earliest locomotives ran on log, not steel rails. The locomotives and flatcars had large concave (hollow) wheels that ran over the logs. This method was used on short rail spurs, while main railroads heading up a valley were built with ties and steel rails. At first, the logs were hauled to the railroad by oxen and horses. Steam donkeys took over in the early 1900’s and yarded logs to the railway, often in conjunction with a spar tree. |
