the eastern end of the CPRR was extended to Ogden by purchasing the Union Pacific Railroad line from Promontory for about $2.8 million in 1870, it ended the short period of a boom town for Promontory, extended the Central Pacific tracks about and made Ogden a major terminus on the transcontinental railroad, as passengers and freight switched railroads there. Subsequent to the railhead's meeting at Promontory Summit, Utah Territory, the San Joaquin River Bridge at Mossdale Crossing (near present-day Lathrop, California) was completed on September 8, 1869 with the first through freight train carrying freight from the East Coast leaving Sacramento and crossing the bridge to arrive that evening at the Alameda Wharf on San Francisco Bay. As a result, the western part of the route was extended from Sacramento to the Alameda Terminal in Alameda, California, and shortly thereafter, to the Oakland Long Wharf at Oakland Point in Oakland, California, and on to San Jose, California. Train ferries transferred some railroad cars to and from the Oakland wharves and tracks to wharves and tracks in San Francisco. Before the CPRR was completed, developers were building other feeder railroads like the Virginia and Truckee Railroad to the Comstock Lode diggings in Virginia City, Nevada, and several different extensions in California and Nevada to reach other cities there. Some of their main cargo was the thousands of cords ( each) of firewood needed for the many steam engines and pumps, cooking stoves, heating stoves etc. in Comstock Lode towns and the tons of ice needed by the miners as they worked ever deeper into the "hot" Comstock Lode ore body. In the mines, temperatures could get above at the work face and a miner often used over of ice per shift. This new railroad connected to the Central Pacific near Reno, and went through Carson City, the new capital of Nevada. After the transcontinental railroads were completed, many other railroads were built to connect up to other population centers in Utah, Wyoming, Kansas, Colorado, Oregon, Washington territories, etc. In 1869, the Kansas Pacific Railway started building the Hannibal Bridge, a swing bridge across the Missouri River between Kansas City, Missouri and Kansas City, Kansas which connected railroads on both sides of the Missouri while still allowing passage of paddle steamers on the river. After completion, this became another major east–west railroad. To speed completion of the Kansas Pacific Railroad to Denver,
