The park area around the beach has been closed for some time now (due to vandalism

).
I noticed this a few weeks back by the sign posted at the handicap entrance at the lower end of the park.
The trailhead at the upper end of the park is still open, and it's posted that you can only hike the first mile and then it's closed after that..:beathead:
As for walking along the railroad right of way (not including the tracks) you are taking a risk when doing this.
Not because of the trains taking you out, but because they have personnel ride on occasion (the electric carts, vehicles?) down the tracks before the freight passes through and they are always on the lookout for anyone who doesn't have permission to be on the right of way. In addition, the engineers are on the look, will call the local dispatch, who probably call the local authorities, and that's when you'll get nabbed.
Being a surveyor for the state I know this because we have to call the railroads and let them know that we will be working near the tracks, otherwise we get an earfull from them.
I guess they don't like to fill out accident reports and/or pick up the pieces of those who don't know how to read "danger - no tresspassing"

signs....
I don't blame them....
Picnic point and Mukilteo parks are still open...
