The ventilation system on the trains is a major weight contributor and power draw. The 7000 series trains weigh way more than the 2, 3, or 6k series. Heated floors, and the lighter ventilation system, could save a lot on the overall weight of the rail cars. Being heavy is part of the operational problems of the 7ks; more wear and tear on the rails, draws a lot more power from the 3rd rail than the legacy trains for all its systems, etc.
