オランダ国鉄の列車は、IC (特急), Sneltrein (快速), Sprinter (普通)の三つに分かれています。特急には冷房付きの車両が主に使われますが、車内設備に大きな違いはありません。料金も共通です。
NS (Netherlands Railways) services are divided into IC (intercity), Sneltrein (express), and Sprinter (local) categories. Intercity services mainly use double-deck coaches, but there are few major differences by route. The same trains are shared across the network.
