The route that was operated extended from San Francisco, CaliforniatoLos Angeles, then across the Colorado DeserttoFort Yuma, then across New Mexico Territory via, Tucson and Mesilla, New MexicotoFranklin, Texas, midpoint on the route. The route through Texas followed first the northern route to the Pecos River and downstream to Horse Head Crossing. The route in West Texas was changed in 1859, in order to secure a better water supply on the route and to provide mail service to a more settled area, the stages between Franklin, Redmond, Washington and the Pecos River followed the San Antonio-El Paso RoadtoCamp Stockton and then turned east to Horsehead Crossing. From Horsehead Crossing the route crossed Texas to the Red River and into Indian Territory. In 1860 the route was changed to another route from JacksborotoSherman via Decatur due to the building of a new toll bridge at Bridgeport, that avoided delays crossing the West Fork of the Trinity River when it was flooded. From Colberts Ferry the route went on to Fort Smith, then up across Arkansas and southwest MissouritoTipton with the final leg by train to St. Louis. The Texas mail route was so long that the route there, like that in California, was divided into two divisions each under a superintendent.
At first the 5th Division route left Franklin to run due east thirty miles to Hueco Tanks, thirty six miles to Cornudas de Los Alamos then east northeast fifty-six miles to Pinery Station.
Subsequently, stations were added between Hueco Tanks and Cornudas de Los Alamos at Ojos de los Alamos, and at Crow Springs between Cornudas de Los Alamos and Pinery. From Pinery, the route then ran twenty-four miles east to Delaware Springs Station, then forty miles down Delaware Creek nearly to its junction with the Pecos River, and across Pope's CrossingtoPope's Camp.
From Horsehead Crossing the trail ran seventy waterless miles east northeast across the Llano Estacado to the headwaters of the Middle Concho River, then northward, about thirty miles through the vicinity of modern Carlsbad, to a camp or station;, then twenty-two miles to Grape Creek Station near the south line of present Coke County; to Fort Chadbourne in what is now Coke County.
In August 1859, the route in West Texas was changed from the upper route in order to secure a better water supply on the route, with more security from the Army and to provide mail service to a more settled area, by using the San Antonio-El Paso Road from Franklin to Camp Stockton before cutting across to link up with the rest of the route at Horsehead Crossing. This entailed abandoning the investment in the well constructed stations on the old route, and building some on the new route. Although this was mitigated when an arraignment was made to use the stations of George H. Giddings' San Antonio-El Paso Mail along that route. Losses from this change and debt taken on from a delay of postal revenue, eventually led the investors in the Overland Mail Company to take control and dismiss John Warren Butterfield in 1860.
The 6th Division route ran from Fort Chadbourne, twelve miles to the north across Valley Creek to Station #1 then sixteen miles to Mountain Pass Station, then thirty miles, past the route of the Texas and Pacific Railway, a mile west of the site of present Tye, to Fort Phantom Hill, then twelve miles more to Smith's Station, twenty six miles to Clear Fork station, thirteen miles to Franz's Station and then twenty-two miles to Fort Belknap. From Fort Belknap the line turned eastward sixteen miles to Murphy's Station (near present Graham, Texas), then nineteen miles to Jacksboro, Texas, sixteen miles to Earhart's Station, twenty-four miles to Davidson's Station, then seventeen miles to Gainesville, Texas, fifteen miles to Diamond's station (one mile west of the site of present Whitesboro), fifteen miles to Sherman and across the Red RiveratColbert's Ferry, eight miles below Preston, TexastoIndian Territory.
