One of the more popular time periods to model is Era I. Era I is desirable because it deals with many of the private state railways from the years 1835 to 1925. The Bavarian State Railways is among the most exciting railways to model in this time period because they incorporated many unique and impressive steam locomotives which were painted in exquisite liveries. The DVI was built in 1880 by J. A. München and it was designed to be used on small local branch-lines hauling both local passenger service and light branch-line freight.
