Have a look at the kind of InterCity trains in the Netherlands
@reaperexpress marveled about
I never marveled about anything. You said you couldn't name any intercity doubledeckers other than those in Switzerland, France and the U.S., so I helped you name some more.
If you had actually read the post, you would have seen that I agree with your position regarding doubledeckers on VIA's network. Portraying me as some kind of bilevel fanboy is doing little other than undermining your credibility.
and take the route from Amsterdam to Maastricht (which is with 218 km about the longest distance you can travel in the country)
The longest NS routes in the 2020 schedule are:
Intercity 900 Den Helder - Maastricht (301 km)
Intercity 2900 Enkhuizen - Maastricht (281 km)
Intercity 3900 Enkhuizen - Heerlen (278 km)
Intercity 700 Den Haag - Groningen (260 km)
Intercity 500 Rotterdam - Groningen (248 km)
The Amsterdam - Maastricht line is a combined segment of routes 900 and 2900, which continue north of Amsterdam to Den Helder and Enkhuizen, respectively. I don't know what the situation was in 2016, it's possible the lines didn't continue beyond Amsterdam at the time.
and you will notice that none of the 7 intermediary stops is skipped by any train
There are 36 intermediary stations between Amsterdam Centraal and Maastricht, and Intercity trains skip 29 of them:
(Amsterdam Centraal)
Amsterdam Muiderpoort
Amsterdam Amstel
Amsterdam Duivendrecht
Amsterdam Bijlmer Arena
Amsterdam Holendrecht
Abcoude
Breukelen
Maarssen
Utrecht Zuilen
Utrecht Centraal
Utrecht Vaardsche Rijn
Utrecht Lunetten
Houten
Houten Castellum
Culembourg
Geldermalsen
Zaltbommel
's Hertogenbosch
Vught
Boxtel
Best <- yes it also means the same thing in Dutch
Eindhoven Breukenlaan
Eindhoven Centraal
Geldrop
Heeze
Maarheeze
Weert
Roermond
Echt <- means "really" in Dutch
Susteren
Sittard
Geleen-Lutterade
Beek-Elsloo
Bunde
Maastricht Noord
(Maastricht)
The Intercity schedule you showed only shows Intercity stations. That particular line only has one Intercity stopping pattern, so that's why you don't see any skipped stations in the timetable.
A small number of Intercity Express services also share the line between Amsterdam Centraal and Utrecht Centraal, stopping at those two stations en route to Köln, Frankfurt and Basel. Customers with NS tickets can ride ICE services within the Netherlands by purchasing a €2.60 supplement.
and the same is true with the three stops between Amsterdam and Eindhoven (the countries' fifth-largest city).
The three stations that intercity trains serve between Amsterdam and Eindhoven are all major hubs in their own rights.
Amsterdam Amstel is a secondary hub in Amsterdam, which is the largest city in the country.
Utrecht Centraal is the busiest station in the country (busier than Toronto Union) and the central hub of the Dutch railway network. Utrecht is also the fourth-largest city in the country (larger than Eindhoven).
's Hertogenbosch is a relatively small city, but it is the capital of Noord Brabant province and is a hub for local trains in the area.
Granted, there probably aren't that many passengers commuting between Maastricht and Amsterdam, but you can bet that the number of commuters between Eindhoven and Maastricht, Utrecht or Amsterdam (and in all cases: in both directions) is considerable.
Absolutely correct. I suspect that the Amsterdam-Maastricht corridor is the busiest in the country, given the huge commuter flows between nearby cities (Amsterdam - Utrecht, Amsterdam - Den Bosch, Utrecht - Eindhoven, etc). Hence the use of 12-car bilevel trains during peak periods.
