The Orlyval / 'Paris by train' signs are well situated and easy to follow.
The Orlyval is the shuttle service connecting Paris's Orly Airport with the city's RER transit network and is chosen by by many as the most reliable way to travel to and from Orly airport and Paris. There a regular service from Orly to Antony RER station, from 6 a.m. to 11 p.m. every day of the week.
These automated, driver-less trains run all day and every four minutes during morning and evening peak periods.
