Transportation in the netherlands

I'm afraid I don't understand your question.

Are you asking for 2 cities other than Amsterdam in the Netherlands to use while you are there?

Or do you want to break the short journey from Amsterdam to Paris? If so, most people use the high speed Thalys train and it is very much more expensive to make three very short journeys on it than one from end to end.

Can you clarify, please?

We have decided to stay 2 nights in Bruges, but would like another 2 nights in another city as well Already have 4 days in Amsterdam & will end up 5 nights in Paris. In other words I have 4 nights to spend between amsterdam & Paris & so far I'm thinking 2 nights in bruge would take up 2 of the 4 days

Almost every city and town of any significance in the Netherlands and Belgium can be reached by train. But if you want something without too much time spent on travelling: have those two days in Dordrecht. Halfway between Amsterdam and Brugge on the main intercity (not high-speed) railway line to Antwerpen and Brussels, where you have to change trains for Brugge. Historical city. Much undervisited. Good base for visiting Kinderdijk with the river ferry (Waterbus).

I can see I need to read more about what trains to use. That's our means of going from one city to next. I was planning to take either a shuttle or train from
Airport to Amsterdam then using the train for reaching stop overs. Looks like we'll need to use a combination. Do I need to purchase a specific rail pass or pay as we go depending on our destination cities.

Not really, you confused us by saying "I will b taking the train from Amsterdam to Paris", When you will be actually taking one train trip from Amsterdam to XXX, another from XXX to Brugge and a third one from Brugge to Paris.
Just decide where you want to go and assume you can get there by train, 99% probably will be able to. Then look up the train times on the Dutch (NS http://www.ns.nl/en ) or Belgian (SNCB http://www.belgianrail.be/en/) railway site.

Within Netherlands and Belgium there is no need to reserve in advance, and no discounts for advance purchase. Just buy tickets on the day at the station. No Rail Pass needed.
You do not need to take a shuttle from Amsterdam airport. It has a railway station underneath the terminal (very common in Europe). Just buy a ticket and descend to the platform.
Trains to Paris are another matter. These do require advance purchase, and are cheaper the earlier you buy. The company is THALYS: https://www.thalys.com/nl/en/

The trains you're likely to use in the Netherlands and Belgium - except the Thalys to Paris - are basically commuter trains, running all day. Only the Intercity service from the Netherlands to Belgium (Antwerpen and Brussel) needs some planning: it runs only once per hour. The other connections are mostly walk up to the tracks and wait for the next train.

Tks. That's what I thought. U have confirmed that
