Rigidbody2D AddForce towards object

Question

So I have a rigidbody2D component attached to my player. I have the player attach and detach to these rails I am trying to build. While on the rails I have the controls switch from the default WASD controls (which work as I want them to) to W and S for going up and down those rails to and from two nodes. Attaching to and from the rails work fine. However, the player only seems to want to move vertically no matter where I place the other nodes.

Put simply, I want the player to move towards and away from the node when pressing W and S respectively.

Here's the code for movement while on the rails (again, attaching to the rail and switching control configuration works as I want it to.)

                 //railroad movement
                 else if (Railroad == true) {
                     dir = Node2.transform.position - transform.position;
                     dir = dir.normalized;
                         if (Input.GetKey (KeyCode.W)) {
                 rigidbody2D.AddForce (dir * movement);
                     }
                         if (Input.GetKey (KeyCode.S)) {
                 rigidbody2D.AddForce (dir * -movement);
                     }
                 }

So what am I doing wrong?

Okay I found the problem, i'm an idiot.

 if (Railroad == true) 
             {
                 rigidbody2D.velocity = new Vector2 (0, rigidbody2D.velocity.y);
             }

This code prevents the player from moving in the x axis at all when on the rails, it was something I added before realizing I might want my rails to move diagonally. Removing it fixed my problem completely. Thanks to Rutter for pointing out the problem might have been a programmatic constraint.
