This is a standard gauge railroad bridge/trestle combination with seven openings.
This bridge is designed to cross a river with an island in the middle. The side with the lenticular thru
truss is navigable. The side with the curved chord deck trusses is not (rapids perhaps). Change to
narrow gauge by changing the name and kuid of the rail to MB_NG_Track_3_rail_only and
kuid:35412:38061.
