Model Railway

This is a photograph of a model of Mickleover Station and it's surroundings as it was prior to closure of the line and the filling of the cutting either side of the bridge. In the foreground is the bridge on Station Road and immediately behind it, the aqueduct which carried the stream above the railway. Evident also is the signal box of which nothing remains.
In the far distance (top left in picture) is another bridge of which only the piers remain, and although there are lots of contemporary photographs, I have never seen one showing this bridge. However  there are some taken from it looking towards the station.
The bridge is unusual as there is a slope across the deck and there remains little or no evidence of any road on the surrounding land so presumably it carried only a farm access track.
Also the remaining piers have at some time been heightened, perhaps to lift the deck to clear increased height rolling stock.  Could be a pantograph or perhaps a wagon for transporting giraffes.
Please comment if you can add anything to the mystery.
Note there is a model railway exhibition at the Derby Roundhouse this coming weekend and it is just possible that the model will be there.
