A great pair of maps of the Denver and Rio Grande railroad system. Both extend to include parts of Utah and New Mexico with lines to Salt Lake City and to Santa Fe in New Mexico. Both have an inset showing the system's interconnections to San Francisco, Eagle Rock (Idaho Falls), and east to the Omaha area. The first map shows less development than the second. The legend locates Lines in Operation, Lines under Construction, Projected Lines, and Stage Roads. The second map shows additional lines including a three-rail track that travels westward from Denver to Ft. Logan. The legend locates Standard Gauge, Narrow Gauge, and Three Rail lines. The maps are undated but county development reflects 1885-1890. The title includes a steam locomotive taken from a picture by William Henry Jackson. Both with blank versos. A great pair of maps that delineate the growth of this railroad, which was famous for its mountainous lines.
