HVAC Sulphur Smell on the HR4000s
I am curious, does anyone who rides the B or D Lines notice a certain smell upon boarding an HR4000 set? It's weird because whenever I smell it, I look around and see if there is anything left on the floor or seats, but to my surprise, they're clean (aside from the foot scuffs on the floor).
