Track layout of Lechmere station and the surrounding area, accurate to 1936 (just before the Harvard–Lechmere line was converted to trolleybus). Black tracks are those feeding into the subway, blue are surface lines, and gray are non-revenue tracks. The track layout is from this 1936 plan. The base map is from 1930; it shows the second surface track on the Cambridge Street side, which was removed in 1933.
