CBTC + Short Turn Terminals = Affordable 40tph. |

Posted by Outside the Box on Wed Jun 12 17:48:16 2013 Considering yard constraints and real estate acquisition challenges, sustaining 40tph, with the train lengths we have today, would require short turn terminals. The presently overcrowded sections would run 35-40tph, while sections farther out get 10-20tph.A key component to a good CBTC system is a good merge management system. It reduces conflicts at merges and at grade crossings. The grade crossings north of 135th st on Lenox Ave Line, and Eastern Parkway-Nostrand merge are 2 key examples. It would cut equipment count, equipment mileage, reduce the time spent running counter peak and empty, and relieve the most crowded sections. |
