On 21 April 2016, I had my First Class France Rail Pass Flexi validated at Basel, Switzerland.
My goal was by the first evening to reach Valenciennes (a city in northern France near the Belgian border) using only regional trains, rather than the TGV (plenty of opportunity for high speed travel later in my trip).
I found the challenge as in making local connections since these days SNCF focuses long-distance passengers onto high-speed routes. All very well, unless you want to experience secondary lines and ride trains off-the well-beaten path.
Thanks to Stephen Hirsch and Denis McCabe who helped with my planning, I traveled on a series of TER trains.
After four train-changes reached my destination 15 hours after I boarded the first train on the French side of Basel’s main station.
