The question came up on one question thread conerning interurban line track quality . Rather than go into detail about what I remember from the riding I was able to do while interurbans lasted on that thred, I decided to start a new thread that should be open to all remembered observations about what track quality was 50 or so years ago.
Here are my memories concerning interurban lines:
North Shore: Smooth, except Greenleaf Ave. street trackage on the Shore Line, and on CTA tracks south of Howard Street on the embankment. The North Shore Shore Line tracks were in better shape than the adjacent C&NW main line!
CA&E Only rough spots on the Batavia branch and alongside the Fox River in Elgin.
CSS&SB Don’t remember any rough spots
Waterloo Ceder Falls and Northern. Rough ride only on the Waterloo - Ceder Falls local car because of frequent freight sidings and their switches.
Crandic Did not ride it. The one interurban I know of with a reputation for rough riding.
Pittsburgh Rys. Some of the local streetcar lines had rough track, but the only interurban track that seemed rough was on the Donora branch bridge and between Charleroi and Rosco.
West Penn. Cinder ballast from coke overns, no stone ballast but still very smooth . Some rough street trackage on the Connoslville - S. Connnolsville local car line.
Laurel Line Smooth ride except for a few spots in Willksbarre
Liberty Bell generally looked awful and rode smoothly anyway
Easton Limited same comment, but speeds not as awe inspiring
Baltimore and Annapolis Not bad but less smooth than most of the others
Quebec - St. Joachim (CN) Smooth ride, but not particularly fast
