    • A door seal for an inside compartment of a railway passenger vehicle. A door that moves on rollers laterally into and from a door opening to a stored position in a hollow portion of an adjacent wall. The lower portion of the door is located adjacent a threshold having a movable, flexible seal that moves between a flat position covering a roller track portion of the threshold to a substantially upright position against the bottom of the door when the door is located in a closed position. The seal is constructed of a resilient material and bends to be urged against the lower portion of the door in such a fashion as to seal out noise, debris, light and the like. When the door is open the seal returns to a flat, horizontal position to prevent an accumulation of debris or dirt in the door track which would interfere with movement of the door.
