Ummm this isn't a new plan.....
http://www.dutchnews.nl/news/archives/2011/10/fewer_trains_will_avoid_winter.php
They said they tried this last winter.

So in reality, there will be one train every hour (if we're lucky)

12 snow days in the past 10 years says it all. It ain't worth heating every turnout (switch), too much money for too little. If it snows plan on being late.

Brilliant plan! To reduce the amount of trains delayed by snow........run less trains in the first place. So simple yet so effective, only in the Netherlands!

I wonder when someone actually invents something sort of plough-like that could be used to clear tracks of snow hmmmm now we only need to think of a name for it?

So with this level of thinking the logical conclusion would be don't run any trains, therefor no delays? Magic.

Wow, this looks like some strategy indeed - no train, no problem.

So, if they are providing half a service on "snow days" do we get to pay half price?
If the train service is halved, what about those trains that currently run every half hour? Will that slip to every hour or will every train become a stop train and it's all the intercities that are cancelled?
Do "snow days" also migrate into "storm days" where there is a chance of storms, wind and it might rain alot?
@ David: very true and how many of those 12 days in 10 years happened last year?
Do these cancellations get added to the statstics reported to Government when they are talking about train punctuality?

I am guessing something like 11 out of those 12 days fell within the last 3 years, but of course it sounds better to smear it out over a longer time period...

This is the same thing they did last year, and it didn't work because (1)it was a different type of snow (remember?) and (2) the state of the railways, ProRail this and that. The fact is that we have more and more snow every winter and NS has no solution. Employers big and small and self employed people will lose income just so that NS does not have to spend on proper infrastructure. Meanwhile, in other countries like Germany and Switzerland (I'm not even talking about the Nordics), life, and trains, will go on and they will not use a couple of snowflakes (or a storm that is many many hours away) as a excuse to stop service.

@Alex: there are no train services in the Randstad that operates with a frequency smaller than 1 train every 30 min during daytime service.

I am amazed how tolerent the Dutch society has become when defending their rights in "3cm" snow days.
Don't you find this grotesque? Really.
Most of the winter in Chicago are with more than 3cm snow and with less than -10 celsius!
Yet, I very seldom experienced any train problems.
Obviously, you live in another planet. The planet of fools and ridicule.
Just send the rail companies home. They are not up to the job.
Dutch people, stop being suckers. You pay a lot of tax. STAND FOR YOUR RIGHTS.

I don't know who the morons are coming up with these statistics, but last year there were 2 weeks of adjusted service because of the frost, and more delays because of the snow. They need to adjust the infrastructure as snow/frost has more recently become a reality.

I don't know about the statistics, but I find many of the comments here not that fair. The Netherlands has one of the most (if not the most) congested national rail system on the planet (more than in Chicago, Germany, Switzerland), so it seems to me that a planned reduction of trains running in severely inclement weather and ensuring they are on time is not so stupid. We will still have more train connections than any of the places mentioned in the comments. Also, the price of the ticket depends on the class and distance, not on the absolute number of trains running. All in all, there are worse things to complain about in the Netherlands, than its trains.
