Answer 2

Answer

• Far too many variable to say whether or not one way is cheaper than another. Some train fares can be really cheap if booked in advance, but that isn't always possible for short trips. And over the holidays some trains may be only be available at full price, particularly for trains from Belgium into France, most of which eg Brussels / Paris require reservation. I am thinking that low cost tickets will have long ago been sold.
• Set against that is the cost of renting a car for a one way trip. If you take a German car to France and wish to leave it there, someone (you) has to pay for the car to be repatriated. Imagine if Texas were a separate country and you rented a car for a one way trip to Arizona. You cannot rent out a foreign plated car, so back home it has to go.
• There are also time advantages on long train trips. You may prefer to travel at 150 - 180mph even if it costs more, rather than travelling in a car at 60 - 70mph on possibly snowy roads. Belgium was whacked by a serious snowstorm a few days ago, chaos abounded!
