International Railroad Discussion > Have you seen a telecopic bridge before? ( Brazil)

A friend asked me if I could get information with fellows here in TO on how the old telescopic railroad bridge model works. We know US had almost all type of railroad bridges developed along the time, so maybe someone here could tell us how this old model works and which engineer or company develped this kind of bridge. 
The pictures shows the Teresa Cristina rwy (EFDTC) telecopic bridge in Laguna SC, in the South of Brazil. 

1 - 3) The main mechanism to move the bridge.

Interesting looking bridge, but I have no further information.

It seems to be a bridge that extended out (telescopic), but looking at the pics I'm not sure how it would do so.

Wouldn't want to meet the guy in a bar who had to jack that thing out.

The old B&W picture in this series give us an ideia how the trestle moves: to the right, inside the other trestle. A friend told me that the was a hidraulic jack to move the small trestle to align the rails too. To open the bridge, the hidrauluc jack lower the small trestle, then it moves to the right. To close the gap, it moves to left, then raise the trestle.

This falls into the class of retractable bridges, but it's the first time I've seen one specifically designed for railroads:

https://en.wikipedia.org/wiki/Retractable_bridge

A while back I posted these pictures of a retractile bridge in Boston (it uses tracks to move the bridge sections):

Ray, your thread is very interesting. It is also interesting discover that the bridge in Brazil could be the only model produced specifc to railroads.

Might be a Longshot, and tuff to find but most bridges in the U.S. have a builder's plate on them.

Yes, I know and I asked the guys there in the South to look for that builder's plate. I hope they can find it.
