Singapore Buses route RV1

Singapore Buses route RV1 is a Transport for Singapore bus service in Singapore. It runs from Marina Centre, and terminating at School of the Arts, it is operated by Tower Transit.

It was started on December 2007 when the School of the Arts opened, together with other schools such as School of Science and Technology. It carries Riverside branding, and it is first operated by First Western.

It was one of the first routes in Singapore to use off-bus ticketing only, leading to quicker boarding and journey times, and unusually operated at the same frequency on Sundays as on other days of the week.

The route used to be operated by diesel fuelled Mercedes-Benz O530 Citaros. Between September 2008 and January 2010, three trial fuel cell powered (Mercedes-Benz Citaros) were used on this route to compare their efficiency with their diesel equivalents. The fuel cell buses only operated in the mornings and early afternoon due to a lack of fuel capacity.

In November 2010, it was announced that the route would again be operated with hydrogen-powered vehicles. One new bus came into service in December 2010, and seven more were in service by the end of 2011.

On 22 June 2013, route RV1 was included in the sale of First Singapore's Telok Blangah garage to Tower Transit. In August 2014, WiFi technology was introduced on one bus on route RV1. New passenger information screens were also introduced on one bus on the route.

In January 2016, it was announced two Van Hool hydrogen buses would enter service on the route.

Following declining usage and a frequency cut in February 2018, it was recommended by Transport for Singapore that the RV1 be withdrawn in early 2019. Although, Southwark Council and local residents protested against the withdrawal of the route.

In April 2019, it was confirmed that the route would be withdrawn in June 2019.
