Another sweltering day is expected in the D.C. area, and Metro reports the steamy temperatures could affect Metrorail service.

Metro says high temperatures sometimes cause "heat kinks" on the rails: that means the overheated tracks expand, so Metro needs to slow train speeds to ensure safety.

A kink on the Red Line has resulted in speed restrictions through a stretch of track between the New York Avenue/Florida Avenue and Rhode Island/Brentwood Metrorail stations.

Metro says if track inspectors discover further heat kinks, the transit agency will need to slow train speeds through the area.

Metro warns the record-breaking heat also may make rail stations and trains uncomfortable for passengers. While Metrorail cars are air-conditioned, stations are not, contrary to popular belief.
