Besides, there's no place to turn a train in a subway quickly, is there? I know that these are not subject to FRA regulations, but, even if there were crossovers from southbound to northbound tracks, wouldn't the motorman have to walk the length of the train to head the other direction, not to mention any brake tests from the northbound control cab?
The Purple in the subway would be the equal to the Red in the subway. They would both make all stops. Chicago is not vested in that idea of "express" like New York.

Do you have any idea why the line north out of the Loop was constructed with 4 tracks? If only 2 are used now, and if only 2 can enter the Loop, what was the thinking behind 4? Some things make one wonder.
Two of the 'L's used steam locomotives. The cars were 46 ft. long. You saved money building as tight as you can. The idea of 55 MPH, air-conditioned, AC technology of today was undreamed of.
When the north side 'L' was opened in 1900, it's competitor wass the cable and streetcar lines. The North side was built with local stations every two blocks (1/4 mile) and express stations every 1/2 mile. It was chartered almost the same time as the other three 'L' companies, but had financial problems that delayed it. Also, except for the Lake Street 'L' Chicago 'L' companies were required by their charters to build "through the blocks" meaning they couldn't build over streets without the permission of the property owners. They could cross streets (and alleys) So they built at the rear of lots next to the alley. Alleys you don't have out East, LOL. If the alleys ran the wron way, th 'L' built on private property which they bought and owned outright.
When they got downtown, there was little room to build, or the land was too expensive, so they sought the property owner permission to use the street. This was expensive too but it was the cost to be the "boss." (Blues tune reference) The north side could only build a two-track 'L' over Franklin and Wells Street. So thats why it's still here today as a bottleneck. Not hardly a bottleneck as in days gone by. Then when you considered the bottleneck that was the Loop, that two-track was a piece of cake.
