^In the case of the South Chicago Metra Electric Branch, I wouldn't want to see surface trains running down the middle of 71st street or Exchange Ave. every 5-10 minutes. That would stall road traffic during peak times on major thoroughfares like Stony Island and Jeffrey and create even more dangerous situations at all of the crossings. It'd be best to build a cut-and-cover subway line for CTA that runs the same route but underground. Population density is higher in South Shore than many areas that are serviced by 'L' with CTA-style headways so it's really a shame that residents there have to wait for one train per hour during off-peak times (and I speak from experience).
