Given that next September I am to make ample use of the Train des Pignes railway, I've been consulting some relevant documents and reviews posted online. Some comments set me thinking. So here I am posting two questions.
1) It seems that passengers often have to travel in crammy conditions. How much is that true for a weekday in late August?
2) Does these apparent "crammy conditions" make the dispatch of a cumbersome rucksack by freight mandatory. If such is the case, how does it work and how reliable it is?
