The passing landscape gives you a frame of reference.
Here's one example. Suppose you're on a train. Now let's further suppose this is a very smooth-riding train and that the windows are covered up and you've never been on a train before. As long as the train is going straight (no curves, no hills) and not accelerating or decelerating, it would be very difficult for you to tell you're moving relative to the outside world: everything in the train is moving at the same speed you are, or, to put it another way, you're all in the same frame of reference. That frame of reference may be moving 60 miles per hour relative to the outside world, but everything you can see or measure appears to be standing still.
If you are analyzing a train, you would typically use one of two frames of reference (or both): the ground, or the train.
The passengers reference point ! The passengers are moving at the same speed as the train.
If you are *not* dealing with special relativity and its effects, then the answer becomes far more simple. If you are not moving and are standing on the ground, then you see a train moving past you a fast speed. In this case, the reference "frame" (not necessarily a point) is you and the object being described is the train. If you flipped the roles, then it would be someone on the train watching you as the train moves. However, since it is from the train's perspective, it does not appear that the train is moving, but rather that you are moving away from the train, along with the rest of the world that passes the train by. This is described as the train being the reference frame and you would be the object described by the train. This is, again, just Galilean relativity. Special relativity puts a few twists on it and has some additional effects.

You would see the other traing going by you at nearly the speed of light. This may seem counter-intuitive, but that's what happens. The speed of light is an immutable constant that does not care about your frame of reference. In the braydeon domain, nothing moves faster than the speed of light, regardless of frame of reference.
usually the motion of your frame of reference is 0. When you are in a train going 50 mph, your frame of reference would be you are going 0 mph and the tracks are traveling at -50 mph.

Riding a train
The frame of reference with regard to postion, speed and acceleration is just your perspective in measuring speed, position, or acceleration. Say you are watching a horse and a train moving alongside each other in the same direction. If you are standing on still ground, you observe the horse and the train moving at a certain speed relative to you. Let's assume this speed is three meters per second. Now suppose you are on the train looking at the horse, which is still moving at the same speed in the same direction. You will see the horse moving at zero meters per second relative to you, because both you and the horse are moving at the same speed. Even though you are both moving, the horse will still move along side you as if you and the horse are standing perfectly still. The frame of reference with regard to postion, speed and acceleration is just your perspective in measuring speed, position, or acceleration.

If you are standing on still ground, you observe the horse and the train moving at a certain speed relative to you. Let's assume this speed is three meters per second.

One may use the concept of relative motion to get an idea about the same. If one object fixes his frame of reference to an object which is stationary or is travelling with same speed and direction,to itself(that is their is no relative motion) the that object shall feel its NOT traveling at all. On the other hand if it feels that wrt. to that frame of reference its speeding or that frame is speeding one gets an idea of travelling fast,fater and so on. Example: Suppose you are in a train and the train is accelerating contentiously to gain speed. A person looks out of the window to see ,say a fixed tree, to move away very fast from his observation. As the train may speed he may observe the tree vanishing away in no time. So he gets the idea of speeding and traveling fast or slow. Importantly if another person who sits in the train observes this person he feels both are at rest and not traveling at all.
Riding the Midnight Train was created in 1986.
