Working on the lift bridge. Below are pictures of some experimentation with the hinge section. The carpeting on the top would seem to indicate that I am happy with how it has worked out 
!
It looks great Dennis! How many tracks will cross the lift up?
Make sure the pivot point of the hinges is higher than the top of the rails. I’ve made that mistake.
Mark, there are 5 tracks crossing the lift section.
When you installed your linear actuator, what type of switch did you use? Do you have a switch on either side of the lift, like a three-way light switch? I am going to use two joysticks, one on the inside of the layout and on on the outside. I didn't know if you had any advice on the best way to install switches for this.
Terry, for sure the hinges are above the rail level. Thanks for the advice!

Looks great Dennis. Very clever idea on the wood with the cuts in it to keep the tracks straight. You and John have some of the cleanest layout rooms I have ever seen!

Dennis, I thought about two three way switches, but decided I only need one on-off or in this case, down-up switch. My thinking was, when I am outside the center of the layout, the bridges will always be up until I walk through to the center. Then I would throw the switch mounted on the inner operating area of the layout to lower the bridges. The switch is easy reach to raise the bridges to get out.
That is how I did it. Actually that would only make sense if there was no reason to operate a train from the short, narrow aisle as I enter the room, or if the door entering the room was right at the layout edge where the bridges are, like Mike G. has. So, I have actually set myself up to lower the bridges by reaching under them if I want to stand in that aisle to operate trains. I’ll see how it works out in normal operations and change to two switches if what I have doesn’t work out well.
Did you use a toggle switch, rocker switch, light switch, ... ?
I get what you are saying, but I am not sure I want to leave the section in the up position when I am not down at the layout. I worry about the weight and the constant stress on the actuator.

I used a hefty toggle switch I had in hand. May have been overkill, but free.
@gunrunnerjohn posted:I guess at close to 78 and still able to crawl under the layout I don't have any complaints to lodge!
However, planning for the future was what the lift bridge was all about, I'm suspect my "flexible" days are living on borrowed time.

Medical Science often comes to the rescue of hobbyists who want/need to scramble under their train layout and extend their hands-on worktime/playtime years with trains. Now 81, I applied another option -- I hire Imeril Johnson (a young hobbyist, now a college student) as a helper when I have a THINGS TO DO list. He does the under-the-table tasks and I do the above-the-table work. An inter-generational solution!

Excellent plan, Mike! It looks like Imeril is a great choice!
I think I'll enlist my grandson, I just have to teach him enough to be useful under there! 
My son Nicholas, who is a member here on the forum (I think he calls himself the Hebanator, a take-off of what my students call me at school) knows more about the "above-the-table" operations. Below the table, he seems to lose interest. And he knows enough about running trains to keep me in the "non-profit" repair business for life !
My son, who will be entering into his sophomore year of college this fall, is interning for a theater company this summer. About a month ago they asked for volunteers to build the set. My son, who has ZERO experience, volunteered but let them know up front he had no experience. 'No problem' they said. He spent about 15 hours over a Saturday and Sunday helping them out. Said he learned a lot. Being on the autistic spectrum he can be a person of few words so I thought nothing of his response.
Two weeks later was Father's Day and like most weekends, I had a baseball game to umpire and away I went. When I came home and after I had showered and changed my son tells me my Father's Day gift is down the basement. A bit befuddled, down the basement I went....and found he'd done this while I was umpiring:
He knew I had to build benchwork for the new layout around a support post and figured he'd save me some time!! So whoever taught him the weekend he spent building the set obviously did a great job!
You never know! And no, he's not into trains at all.
Dennis - Thanks for your idea on alignment pins - I never would have thought of it and ordered a set from Amazon as I will need a lift out section myself.

Greg, your son did a great job!
John, we all could use a grandson who can work under the table.
Wow Greg, I am with Mark, your son did a great job! A truly inspiring story.
Greg,
No problem! I'd like to see some close-ups of the joints/corners of the benchwork. It looks good! Drill holes and run bus wires before you put the top deck on. It REALLY helps!!!!

Any time I am mentioned with GRJ, I must have done something right! Hangin' with him gives me "train cred" 
!
It looks good, Dennis!!
