Two more companies have climbed aboard the Extreme Model Railroad and Contemporary Architecture Museum.

IBerkshires.com reports that EMRCA Inc. has announced that Skanska USA and the Gilbane Building Company have signed on to build the proposed 83,000-square-foot museum near Western Gateway Heritage State Park.

From the late 19th century through today, the museum is expected to take visitors on a tour of architectural and railroad history with more than 1,200 scale model buildings and 100 scale model trains in a theme park-like atmosphere catered to families, railroad enthusiasts and architecture fans alike.
