Warren Street is located on a bit of a gentle curve and its two platforms are on each side of the intersection with Warren Street and trains stop before crossing the intersection. The platforms differ significantly: The outbound platform is just a small sidewalk with a yellow tactile warning strip, and is on the same block as the inbound platform for Allston St. The inbound platform also includes a 3-wide rusting metal shelter with white plastic dome roofs typical of bus shelters. There is also a jersey barrier along this middle portion of the platform with entrances at each end.
