allow for the construction of the Black Rock swimming pool. The new Black Rock station opened in May 1937, still with two platforms. The station building was again rebuilt in 1948 in Art Deco style, still with two platforms, although from the mid-1960s the south platform was abandoned. In the 1980s the second (south) platform was restored and used for special school visits trains, operating around the timetabled service. This was short-lived, and in 1989 the south platform track was lifted. The station was briefly renamed Marina Station in the early 1990s, but was in turn demolished in the mid-1990s during a storm drain project, with a new Regency style station building opened in 1998. This new station, which reverted to the original Black Rock name, was provided with only one platform (plus ticket office and toilets), and remains in current use. No other stations are in current use, although there have been halts associated with intermediate passing loops. Former intermediate passing loop halts have been known as Sussex Square (or Lift), and Kemp Town. There was also a temporary Black Rock station constructed, with platform and booking office, during the storm drain project of the mid-1990s. Signalling The line is single throughout, with three passing loops - one at Halfway station (previously known as Paston Place and Peter Pan's Playground), and two others roughly midway between each terminal station and Halfway. The passing loops are equipped with spring loaded turnouts. These are set so that trains entering a loop are routed to the left track. Trains can exit the loop by pushing the switch blade to the appropriate position. In normal service two trains operate from end to end, passing at Halfway station, and there is generally only one train on each single track section at any one time. This is sufficient to provide a 15-minute interval service. Drivers are now equipped with radios which allow communication between themselves, stations, and control. Nevertheless, the line is operated using single track tokens. There are four colour coded tokens, one each for the sections between Aquarium and the first passing loop (red token), the passing loop and Halfway (yellow token), Halfway to the next passing loop (blue token), and the passing loop to Black Rock (white token). In practice, the two pairs of tokens (for the two sections west of Halfway, and for the two sections east of Halfway) are permanently
