As the vision was translated into reality, the original concept was trimmed to a system in the Phase 1 plan, published in 1971. This plan involved two of the original six lines: a northwest line from Downtown Baltimore to Owings Mills and a south line to Glen Burnie and the airport. Phase 1 was approved for funding by the Maryland General Assembly in 1972. In response to crime concerns of Anne Arundel County residents, the MTA eliminated the south line from Phase 1 plans in 1975.
