Hello!
My mom and I are booked on the Loire to the South of France tour that starts June 19. We arrive in Paris on June 18 at and we'd like to go directly to Chartres. (I should add that I'd love if we could arrive earlier, but I am limited by my schedule working in education).
From what I can find, it's typically a fairly short (1 hour to 1 hour 15) TER ride from Gare Montparnasse. However, when I plug in my exact date, I am finding very few options and they are taking much longer and include a stop in Le Mans, which is way past Chartres. (I am seeing this on Trainline.eu and the SNCF website). I should also add that bahn.com shows the shorter journey on TER. Am I just looking too far in advance? I'd like to get this sorted so that we can decide if it's best to stay in Paris for the night, especially if there is some sort of service disruption on that route. Thank you!
Update as of 6/15- we heard from the tour department at RS and there is in fact rail work on the way to Chartres this weekend. Looks like we will be looking in to a private transfer. I wanted to share in case anyone else was in the same boat.
