In 2020, STIB—the inter-municipal transport operator for Brussels—entrusted TootBus, RATP Dev’s Sightseeing subsidiary, with the management of the Hop-on Hop-off tourist buses in Brussels for a launch in 2021. After having been shut down for a year, the Brussels tourist buses have now resumed their activity. To mark the occasion, RATP Dev and STIB are inaugurating the world’s first fleet of fully electric tourist buses.
