Posted by Jackson Park B Train on Wed Oct 22 01:17:57 2014, in response to Re: As America ages, public transportation will grow, posted by AEM-7AC #901 on Mon Oct 20 14:26:47 2014. Having lived in Chicago where CTA did that on the "North South Through Route" which from the north portal of the State St Subway south was only 2 track, and riding the Illinois Central Electric w/ a 4 track main from 115th 50 51st and then a six track main to 12th St. I have experience of both ideas. CTA was signaled for 90" headways in the 50s, the IC not quite that tight, but 20 mph faster. Having the flexibility of express tracks is highly valuable both for total throughput, and for skipping local stops on rides of longer distance. It is also more convenient for riders o have trains to different destinations use different sides of a platform. |
