Alignment Pin Catchers - What To Look For?

I'm currently working on a train elevator for my model railroad, which will be used to lift trains from the lower level to a second deck on my model railroad. The main problem will be alignment, and I've already got something in mind.

What I'm looking for is a metal cutout with a 2D cross-section of a funnel. Something that looks like this:

The idea is that as the elevator raises into position, the cutout catches a peg on the end and uses that to line it up. Thing is, whenever I google or search Ebay for alignment pin, all I get are automotive components.

Can anyone point me in the direction of what I'm looking for?

I've seen multilevel storages for model trains using elevators. No problem. You could use a nail, bolt, some iron piece in the moving bridge. Then use a proximity sensor, on the stationary track bed, that reacts on iron. Trim it to ho´rizontally proper height.

Are you looking for a design for something that you will fabricate or a product that you can buy?

In either case a diagram that illustrates how your system should work would be a big help.

There's nothing ready to buy I will say. There's no market for this very special build. The trick is to store not running trains in the smallest possible volume/area. When being short of area, go for a multi level store using height and use like a lift to move trains from the railroad into the store.

Well built guiding rods are needed for the sidway precision and electrical stuff for hitting the "floor" accurately.

Now I found the word. It’s a very special kind of Shadow Station, a great train park.

It looks like I'll have to have something fabricated. The idea is that it's a sort of 2D funnel that pulls the elevator into alignment as it raises or lowers into position. Microswitches or some other sensor will be used for the Arudino cutout.

I'm thinking 3D printed aluminum via Shapeways.

What is the issue needing fabricated stuff? I don’t get that.
There are several Youtube videos showing various things like I think You aim for.

Hi, Why metal? Can't you make something out of plastic? OR File the shape out of a thick piece/strip of metal?

Tom.. :)

That seems overkill.

Why not just use two pieces of 90degree angle - brass, aluminium or plastic - mounted with the angle facing upwards. The rising piece will slot neatly into the fixed piece.

Have a look for hi-go speaker spikes on eBay , might be what you are looking for .

Now that's elegant.
