Good government and business groups have urged state legislative leaders to oppose a renewed push by the Transport Workers Union (TWU) to require two-person crews on every subway line currently uses. The coalition, signed by leaders of Reinvent Albany, the Citizens Budget Commission, and NYU’s Marron Transit Costs Project, argued that the bill would disadvantage the MTA from expanding one-person train operation (OPTO) to more subway lines. Most subway lines currently operate with two-man crews, except for the three shuttle services and certain lines during off-peak hours. The bill, sponsored by state Sen. Kevin Parker and Assembly Member Monique Chandler-Waterman, is aimed at protecting conductors, who would be replaced by automated systems. Critics argue that the legislation is necessary as conductors are essential to safely evacuate trains during emergency situations.
