The original Bug Line was small branch of the Milwaukee Road
that ran from Granville to North Lake, Wisconsin on the old "Northern division".
The original line was built by the Milwaukee, Menomonee Falls & Western R.R., in 1890
from Granville to Sussex to serve a number of Lannon (limestone) quarries in the
area. It was eventually extended to North Lake in 1897. It was acquired by the Chicago
Milwaukee and St. Paul in 1900.
I model the line as it would have appeared in the mid fifties. By that
time the thrice-weekly trains (M-W-F) were no longer listed as trains number 333 and 332
but instead were run as extras. The normal power in the early fifties was K1 Prairie #926
so the trains ran as Extra 926 East and West, displaying the requisite white
classification flags. By this period much of the freight business was gone and the
"mixed" (passenger and freight) service classification had been changed to
"freight". It is a sleepy patrol heading for eventual abandonment by the 1970's.
You can still ride the North lake - Merton section today on the Kettle
Moraine Scenic Railroad. The rest of the route is a "Rails to Trails" convert
from Merton thru Sussex.
