Answer:
The Baltimore and Ohio Railroad was constructed to run from Maryland to Ohio.
Step-by-step explanation:
The Baltimore and Ohio Railroad (B&O) is the oldest railway company in the United States. It was the first company to offer a service to the public with fixed schedules for both freight and passengers. Its first line connected the port of Baltimore (Maryland, United States) to the Ohio River near Wheeling (West Virginia, United States).
It was classified as an American Class I railroad. It existed from 1827 to 1986. Today, it is part of CSX, which originated from the merger of many other companies on the eastern coast of North America.
