This weekend, the RailAdvice team went on their annual study tour. This year we travelled to Paris and visited RATP, which, among other things, both owns and operates all public transport in Paris. We visited one of the largest metro workshops, where we learned about the metro and especially RATP's future ambitions with battery operation for maintenance machines. Interesting learning and we were well taken care of by RATP! We also had some spare time for delicious French food and sightseeing in Paris.
