One of Forbes's notable contributions was his involvement with the Michigan Central Railroad, which played a crucial role in connecting Chicago with the East Coast. He served as the company's president from 1859 to 1863, during which he helped expand the railroad network and improve its financial stability.

Furthermore, Forbes was deeply involved in the construction and development of the Hoosac Tunnel in Massachusetts. This project aimed to create a railway tunnel through the Hoosac Mountain, and Forbes played a vital role in securing the necessary funding and political support for its completion.

Aside from his business endeavors, Forbes was known for his strong abolitionist views. He actively supported the anti-slavery movement and played a part in organizing funding and aid for escaped slaves through the Underground Railroad.
