Fares were stored in a money room at 370 Jay Street in Downtown Brooklyn starting in 1951, when the building opened as a headquarters for the New York City Board of Transportation.</ref> The building is close to the lines of all three subway divisions (the IRT, BMT, and IND) and thus was a convenient location to collect fares, including tokens and cash, via money trains. Passageways from the subway stations, including a visible door in the Jay Street IND station, lead to a money sorting room in the basement of the building. The money trains were replaced by armored trucks in 2006.</ref>
