Review of conceptual illustrations

IMG_0696IMG_0697IMG_0698

Details of bridges and supporting structures are well researched and documented. Scene is designed to depict a river crossing by a Front Range short line that replaced a trestle used by the preceding narrow gauge railroad. The east end was washed out by a flood during WWII and wartime restrictions dictated use of available materials rather than new construction. The plate girder bridge was used to span the new channel formed by the flood. It was salvaged from a class 1 road and the trestle approach repaired. A pile pier was used on the east end for speed and economy.

Bridge deck structures and trestle follow D&RGW standards. Guard rails are fully spiked as per D&RGW standards.

The cut on the west end is narrow by Standard gauge standards, but it was excavated by a narrow gauge railroad and with no demand for oversize clearances, it was never widened. Short lines are notable for their economics.

The display breaks down into two five foot modules after the through truss is removed. The modules and legs weight appox 50#.
The structure will support a 200# load without damage.
