This brings back memories for me as well. My first house in West Allis (sub or Milwaukee) was two block from the main building for the interurban. One block south of Wisconsin State Fair Park. There were three very large rosettes for the power to the over head lines. It went southwest to Big Bend were there's still signs of it. Then on along the Fox River to Mukwonago were there's still the piers for the duel tracks to cross. Just beond US43 & 83 is were the tracks still exist and go on to East Troy were they end. There is a repair shed filled with old rail cars and two interurban cars. Also a depot were you can ride back to Elegant Farms Mart in Mukwonago. There's still over head lines and they want to run the interurbans again. These were not just for freight but also took the big wigs to there big lake cottages. And the POWs to there jobs.
