It all started with a new bathroom built in the loft. The builders left so much timber behind that i decided to build a garden layout in OO. My wife then suggested that due to our weather here in the UK, South Wales , a layout in the garage might be a good idea, so i said ok, if you insist, lol. Over the next few days i will upload photos documenting my progress with The Blue Line Garden Railway, The Coegnant branch of the Blue Line, the Colliery and the Air Line bascule bridge.

An excellent work there, Paul. This is definitely a great bridge. Lucky for me, I will start building a bascule bridge in next few days, and this will definitely be a great reference. Is this operational-I mean are there any movable joints to actually lift the bridge?

Waiting to see more progress...

That is a beautiful bridge! From the looks of the pins, I would guess it to be operational. I would love to see it in place and operating.

Thank you for your kind comments. The bridge was built to replace a board which slotted into the gap in the layout by the door into the garage.

The board was difficult to line up accurately, but the new bridge drops down into place every time and the trains run across with no problem. Here are some photos of the construction of the bridge and photos of the real bridge.


The bridge was drawn using autocad and plotted out.

Thanks

The bridge was built using strips of lime which were left over from the first planking of my scratch built model of the Santisima Trinidad. When glued together to form an I beam they are very strong.


And Here are some photos of the bridge in various stages of lifting

Not shown yet are the operating arms. at the moment the bridge is hand operated. I hope the diagram below shows how the bridge worked.

Its the operating strutts that raise and lower the bridge which is balenced so a relatively small motor (75 Hp) was used

Hi Paul and welcome aboard AMR.
That is a very nice bridge that you have built there and you should feel rightly proud of your work. Will you motorise it as the original 1/1 scale bridge was? How long and high is it?

Just keep it coming and we will watch.

Doug.

excellent!!! This will undoubtedly be the frontal piece of your layout. Thanks for the detailed description and photos (My reference just got stronger ).

By the way, I am eager to know about your layout as well. Could you please start a thread on that?
Thanks
