RER line A is a permanent worksite. Every night between 1:30 a.m. and 4:30 a.m., the line is teeming with activity: teams are dispatched all over to carry out preventive or curative maintenance operations when defects requiring intervention have been observed over the previous days.
What is difficult about it? Organising everything successfully so that passengers who take the line the next morning do not notice anything!

The 600 staff members working every night succeed in renewing 30 km of rail track every year - and this on a line with the highest level of traffic in Europe, with nearly 1.1 million passengers every day.
If our work is done properly, no one notices it. We are proud when no one talks about us and when we are congratulated once a year because we have achieved our service quality goals!
