Reply to comment by sumpdiddlyump_ in New 8000 series Metro trains will have heated floors and charging outlets by Yaratam

It's replacing the forced air heating on current trains as it's more efficient. So it's actually a core function and not a gimmicky add-on.

Plus it's gentler than having a blast of hot air on you.

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.

The 7000s being heavy is also why they’re fortifying the redline pier caps on the elevated sections of the track!

Potentially a silly question, but given that we know airborne pathogens are around and here to stay, wouldn't a strong ventilation system be something to prioritize?
