请教几个关于比利时Rail Pass的问题

1.如果从布鲁塞尔出发到布鲁日, 途经根特,搜索到的信息是中途可以在根特下车,只需要填1格:布鲁塞尔出---布鲁日, 但是我在铁路官方网站得到的信息是这样的:

If you'd like to break your journey, then fill in two lines on your Pass: the destination station on the first line will correspond to the station where you want to break your journey

**Break in journey

There is a break in the journey if the passenger intentionally misses the first connection which would take him to his destination fastest.

请问这样应该如何理解呢?


2.我可以用Rail Pass从布鲁塞尔往返Arlon或者Vise这些边境城市吗?以下是官方网站的信息:

With a Rail Pass, you can make 10 single journeys between two Belgian stations of your choice (frontier points excluded)

**Frontier point

The concept of "frontier point" is used for pricing tickets. This does not mean a station for passengers to board or alight. The frontier points are: Roosendaal-Grens, Visé-Frontière, Aachen-Süd-Grenze, Gouvy-Frontière, Sterpenich-Frontière, Jeumont-Frontière, Quévy-Frontière, Blandain-Frontière, Tourcoing-Frontière

我不明白他们Frontier point的定义


3.要是可以用pass前往Vise, 但是中途必须在liege转车,那么我应该填1格还是2格?


谢谢高人解答...要是以上答案皆否,我必须重新安排行程,原本打算2个人共用1张pass游玩布鲁塞尔,根特,布鲁日,卢森堡(到Arlon)和Maastricht(到Vise)的
