 The NC & WR's other planned extension was to branch from the BS & WR's curve under Park Crescent. It was then to curve eastwards under Regent's Park and then run under Longford Street and Drummond Street to end at a station on the west side of Seymour Street (now Eversholt Street) under Euston station. An intermediate station was planned for the junction of Drummond Street and Hampstead Road.
