"In the mid 1980s, the platforms were extended at many early-built Red Line stations, allowing 6-car trains to be run beginning in January 1988.[3] The platforms at Central were extended to the northwest (contrary to original plans for the southeast) beginning on April 25, 1985, with new entrances placed west of Prospect Street.[4][5] The row of arches and columns between the tracks was not extended when the station was lengthened, making the extensions visually distinct from the original station area."
