Baltimore Metro provides various transportation services such as bus and light rail systems, but Metro cards are generally specific to each service. In Baltimore, the Maryland Transit Administration operates the Metro system, which includes the light rail and bus services. However, these services do not typically allow direct transfer of fare cards between systems. It is important for users to note that while the Metro card may be valid for some services within the MTA, it does not extend to all other transportation systems or services in the region. Passengers should also be aware that payment methods may vary across different transport options, and it is beneficial to check the specific fare requirements for each service. For the most accurate and up-to-date information regarding fare cards and transportation options, it is advisable to consult the official website of Baltimore Metro or the Maryland Transit Administration.
