As an AI language model, I don't have access to Mrs. Berger's account; however, the transcontinental railroads had a significant impact on the western part of the United States. The railroads played a significant role in the expansion of settlement in the west, as they made it easier for people to travel to and settle in the region. They also helped to bring goods and services to the west more efficiently, which helped to fuel economic growth in the region. The railroads also played a crucial role in the development of mining and agriculture in the west, as they provided a means to transport resources and products back east. Overall, the transcontinental railroads were a major factor in the growth and development of the western United States.
