Answer 1

In the new router (>= RC.0) in the AppComponent this can be done with

  import 'rxjs/add/operator/first';
  ....

  constructor(private router:Router, private routeSerializer:RouterUrlSerializer, private location:Location) {
    router.changes.first().subscribe(() => {

    let urlTree = this.routeSerializer.parse(location.path());
      console.log('id', urlTree.children(urlTree.children(urlTree.root)[0])[0].segment);
    });
  }

(to get the 2nd segment)

In MyComponent this is easier:

routerOnActivate(curr:RouteSegment, prev?:RouteSegment, currTree?:RouteTree, prevTree?:RouteTree):void {
  this.id = curr.getParam('id');
}
