I had the option of a Duck under or a gate to get into the trainroom, i decided on a gate but this design can be used as a removable bridge if desired, It is basically a big box tapered like a wedge at the ends so when it’s closed it will always locate in the same position 
as you can see the tracks on two levels.
To start i built the benchwork at both sides of the walkway, (use the best quality lumber you can get and let it aclimatise in the trainroom for a few months so you don’t get distortion) make sure it is level. make a template from stiff card to work out how much of an angle to put at the end, if you make the gate square you will notice that when you open it the opposite end from the hinge moves out
, this is the reason for the wedge shape. i cut out four end sections, two are secured to the benchwork and the other two are the matching sections for the end’s of the gate, i then built the box section gate to match the opening, when this is done fit the hinges and put guides at the bottom (attached to the benchwork) these will guide the gate into position every time. when it came to laying track i used flex track, it was glued into position then cut at the gate joints then wired as required, don’t forget the power cut off switch or some device to stop runaway trains learning to fly
as an alternative you can delete the hinges and use it as a slide out bridge.
Steve: Thanks for the explination on the swing out. I printed it out but the drawing didn’t print. The pictures will be enough, I think.

Steve,
Thanks for posting such great information on your gate.
The plans for my layout include a gate similar to yours; but will have to accomadate 4 levels of tracks. My around-the walls 2-deck layout requires a 2-turn no-lix to link the two decks which account for 2 of the levels needed on my gate. The other 2 levels are to allow for a full circle on each deck.
I’m still trying to sort out the details; but I’m thinking of making a door-like frame, from which I’ll hang “shelves” on which each of the levels can be run at the appropriate grade.
Like you, I had accounted for angling the gate’s ends to allow it to swing more freely and align properly when closed.
If I ever get started on construction (other priorities have been gobbling up whatever spare cash I have), I’ll be sure to take photos along the way and post them.
I like that gate, Steve, and I think it will be adaptable to what I need when I start putting my staging yard in this summer on the other side of the garage. I especially like the ‘wedge’ design, which look like it ensures proper track alignment when in place. I kept thinking about a duck-under, but not at MY age, LOL!
Thanks for the information. BTW, really LIKE that new photo!
Tom [:D]
can I asak a stupid question… how does the track make the connection? when you swing it back…
BTW great idea… I am going to do something like that…
