In order to ensure the best possible travel conditions for all twelve municipalities in the Saint-Quentin-en-Yvelines conurbation outside of Paris and to promote local economic growth, SQYBUS – an RATP Dev subsidiary founded in 1975 – offers modern and comfortable transportation. Today, it operates the second-largest transportation system in the greater Paris region after the RATP.

RATP Dev Suisse Transport Public has been active in the canton of Geneva for over 40 years. The company’s core business is operating regular routes through subcontractors for Geneva Public Transport (TPG).

An urban transportation subsidiary of RATP Dev Suisse, RATP Dev Suisse Transport Public has made it easier for students, tourists, local residents and professionals to travel, both locally and across the border. 

The Hong Kong tram, with its double-deckers, has become a symbol of the city. It celebrated its one-hundredth anniversary in 2004, yet still looks as young as ever.

Hong Kong locals are particularly fond of their tram, the subject of many a childhood memory or family anecdote. It has garnered the affectionate nickname of "Ding Ding".

The tram's main challenge is to transport 200,000 passengers every day in one of the most densely populated cities in the world. All the while, it remains one of the most environmentally-friendly forms of transportation.

Seoul Line 9 – Seoul's largest subway line – is owned by RDTA, a joint venture of RATP Dev and Transdev in Asia. When its operation and maintenance contract was renewed for 10 years in 2013, the level of satisfaction was in keeping with the importance of the mission.

Line 9 carries 500,000 passengers per day in one of the world's most densely populated cities, linking the Gangnam financial and tourist district to Gimpo International Airport.

RATP El Djazaïr was entrusted with the operation and maintenance of Algiers metro line 1 when it first opened in 2011. Today that line is 12 kilometers long, boasts 14 stations, and carries 200,000 passengers every day.

Tootbus Paris is a practical and enjoyable alternative for visitors in Paris. Tourists can enjoy a unique view of the iconic monuments and places of the capital through an exclusive experience from the upper deck of the bus.

They can hop on and off at  Tootbus Paris -specific stops that are always near one of the city's attractions.

The company has integrated the broad diversity of its customer base in its offering and now offers new audio guides in English and French as podcasts via the Tootbus app.

The safety of COM'BUS passengers is the priority of this RATP Dev venture. To this end, concrete action is taken and ground teams are reinforced on the routes. Around twenty ticket checkers and station attendants work hard every day for the well-being of their customers, making sure they travel stress-free.

Here's what's new:
The COM’BUS maintenance garage provides services for other RATP Dev transit systems, including Tam, Mobicité and Ligne Express.

Offering optimal, quality DRT service at the best price, and helping people with disabilities maintain or regain independence through high-quality, customized, affordable transportation*. That's the challenge RATP Dev's subsidiary, FlexCité, has met head on for over 15 years. It is also a transit system with "Bientraitance" certification for outstanding service.

Gem'Bus is a subsidiary of RATP Dev and a partner of the Geneva public transit authority. For seven years it has carried Swiss and French commuters smoothly across the border between Haute-Savoie in France and downtown Geneva.

To meet the needs of cross-border commuters even more closely, Gem'Bus amped up its service. Route D buses now come by every six minutes at rush hour. Automatic ticket distributors are also provided to speed up boarding.

Thanks to the know-how of this RATP Dev subsidiary’s employees, the inhabitants of Bourges have been enjoying a more ecological network of 65 vehicles since 2011. Our commitment means a fleet over 50% of which is made up of buses powered by natural gas (NGV), including 11 hybrid gas buses.
