This is our fourth bridge project. The prototype bridge is the B&O double track Pratt Truss pin-connected mainline bridge found in Ilchester, MD on the B&O Old Main Line. The bridge is 163 feet in length and capable of permitting double stack traffic. The single track version retained all of the ornate structural details that is found on the prototype. As always, super details are found throughout the bridge including the super-fine grated walkways. Full details will also be found in the floor system.
