All that coal was of little value without a way to move it to markets—Denver for factories and homes, Brighton for railroads, Boulder and into the mountains to power hardrock mining and precious metal recovery. The race for railroad connections was on! When the transcontinental railroad was completed through Cheyenne (1869), it was quickly followed by the Denver Pacific (Denver to Cheyenne) connection in 1870. Since Erie was the center of coal production at the time, the new railroad built a spur from the mainline in Brighton west to Erie, and the first coal trains starting rolling over the Denver and Boulder Valley Railroad by 1871. In just a few years (1873) the line stretched west through Canfield, Leyner, and on to Boulder.
