Mickey Mouse Wall access??

What is the story with access to Mickey Mouse Wall?

According to the description posted on MP:
"At an intersection with a road and a gate on the right continue straight onto a double track for about 100 feet and then take a right onto a single track."

We hiked up that way and at the single track, there is a sign that says "climber access trail only, dead end"
Further up the trail, just before you get to the railroad tracks, there is another large sign saying "Raptor Nesting Closure. Area behind this sign is closed between February 1 and July 31."

We hiked past that and then did not go through the tunnel, but rather the use trail around it, thinking it would be safer. When we got out on the other side of the tunnel, we were about 15 feet from the railroad tracks and there was another raptor closure sign. At this point a rail road worker saw us and started yelling, being quite rude, and threatening to call the railroad police.

We had not yet stepped on the railroad tracks (there was a train stopped through the tunnel). We had just passed a raptor closure sign, and I'm not sure what laws apply. The sign, by saying the area is closed between Feb-July, implies the area to be open the rest of the year.

So what is the story? Can the railroad really have you arrested? I can maybe see it is illegal to cross the tracks or run through the tunnel (we went around it), but this rude guy was being a jerk and telling me all the area around was railroad property, including the hillside we just came up which had several Boulder Open Space signs on it, so I think he was just being full of shit and threatening us...

So, is OSMP implicitly encouraging people to trespass? They have a signed trail that dead ends at the railroad. What other purpose could that trail serve? Obviously its users are intending to trespass. If it is illegal, why do they even sign it as a climbers' trail?

Times change I guess. 15 years ago we used to just hike in along the tracks from Plainview, through all the tunnels, and the rail workers would just wave at us.

According to the OSMP web site Mickey Mouse wall is open now. No accounting for crazy RR workers, though.

Maybe the hike up to remove the closure signs is a little too strenuous for the OSMP folk.

The signs are permanent and are there year-round unlike other
areas in OSMP where it's just a laminated piece of paper.

You are trespassing if in the tunnels or walking
the tracks, unfortunately the only way from
the east to get to MM is by crossing the tracks.

There is a way to come in from the top but it’s kind
of convoluted and would be difficult to explain online.

My friends and I got busted in Glenwood canyon years ago. It was dropped because a maintenance guy let us walk over and down a ways. I hope he didn't get fired.
Bottom line in the canyon anyway... they own 100 feet each side of the tracks. They were their before the forest service.
When I called Pacific Union, I was told by a HIGH up that next time we would go to jail. When asked about the flag flying on the other side of the tracks he said... "If we ever catch them, we'll prosecute to the fullest extent of the law."

That's how the west was 'won'.
