Transportation

Company buses

The CEA has two types of company buses, which can be used by anyone working in the IPhT:

Navette mutualisée (shuttle shared with other companies) which only go to Porte d'Orléans, but run at a few different times every morning and every evening. Here is the schedule (November 2018).

CEA buses that go from the main CEA centre (a shuttle is available between the lab and there) to many places, including inside and outside Paris, but only twice a day: once in the morning and once in the evening.

Information for both the types of buses is available at: http://www-saclay.cea.fr/Phocea/Page/index.php?id=502

To receive an SMS if buses are cancelled or running late, go to www.cea-infobus.fr and create a personal account. There is also an app that lets one follow the position of the buses.

Public transportation

The region Ile de France has a journey planner: https://www.vianavigo.com/

RER

The RER is a regional train that runs from Paris to Massy-Palaiseau, Le Guichet, Orsay and Gif. People often come to the lab using the RER and take a bus either at Massy-Palaiseau or Le Guichet. Note that the RER is generally considered to be rather unreliable and has frequent perturbations.

It is also possible to come to the lab by foot directly from the RER station La Hacquinière. It takes around half and hour and involves walking in a pretty steep forest which is not lit up at night: http://www.lsce.ipsl.fr/Images/Page/1/Gif-Orme.jpg

Buses

Three bus lines arrive at Orme des Merisiers, which is the closest bus stop to the lab:

Line 9, which comes from the RER station Le Guichet: https://www.transdev-idf.com/ligne-9/les-ulis-saclay/006-006

Line 91.06 which comes from the RER station Massy-Palaiseau: http://www.albatrans.net/

Line 91.10 which comes from Orly airport, through the RER station Massy-Palaiseau: http://www.albatrans.net/

There are night buses from Paris to Gif, Orsay and other places: http://www.noctilien.fr/

Navigo pass

You can travel throughout Ile de France using a Navigo Pass. The monthly cost is below 80 euros. Your employer is required by law to reimburse half of this cost if you use public transportation to go to work. You just need to provide the CEA with the receipt for your monthly or yearly subscription.

If you lose the receipt for a Navigo recharge, go to an RATP office (which are in large metro or RER stations) and they can give you a statement with an official stamp.

Bikes

There are recently built cycle lanes around the lab. However do note that the lab is on a plateau and therefore coming by bike might involve a steep climb.

Three IPhT bikes are available for temporary communal use. Get in touch with Emmanuelle Laborderie to use them.
