Charles Street Trolley

The Charles Street Trolley is a proposed streetcar line running through northern portions of Baltimore, Maryland, United States. Kittelson & Associates, Inc., a consulting firm hired by trolley advocates, estimates that the line would be likely to carry 2.5 million riders per year.

The proposal is backed by a public-private group known as the Charles Street Development Corporation. A second group, known as Friends of the Trolley is also backing the project; it was reported in November 2011 that FotT had hired a community organizer. As envisioned, the line would probably use modern, low-floor light rail cars, but the use of newly-built replica-vintage rail cars is an alternative also being considered.

A website for what appears to be a third group—the Baltimore Streetcar Campaign—is also active in advocating for a Charles Street trolley plan.

Certain portions of the proposed routing would be similar to that covered by the Maryland Transit Administration's proposed Yellow Line. , the proposed alignment also overlaps significantly with a proposed extension of the Charm City Circulator.

While the proposed trolley is not a project of the MTA, the two groups have expressed a willingness to work together on certain elements of a transit plan for the area involved.
