Posted by Outside the Box on Wed Feb 29 11:17:19 2012, in response to Re: R-179 order saga, posted by Avid Reader on Mon Feb 27 20:54:28 2012. 67' cars with 5 sets of doors per side to decrease dwell time.51' truck centers. Interior arrangement similar to R110B to improve passenger movement within cars and interior space utilization. Covered vestibules that allow safe movement between cars while in motion. 8 car sets for BMT eastern division platforms. 9 car sets for 600' BMT southern division platforms. 10 car sets for IND 660' IND platforms. Add Li-ion capacitor for low capacity regenerative braking. This will allow train systems (HVAC, lighting) to remain powered for extended periods of time during power outages. It also reduces the peak power demands on the electrical system during acceleration from stop. A larger system would allow a train to crawl into the next station during blackouts. http://en.wikipedia.org/wiki/Lithium-ion_capacitor Local door controls (locked/unlocked from conductor/TO cab) that passengers activate that reduces door opening and closing, and heating/cooling losses. Sophisticated door controls that allow selective door opening/unlocking of all doors from one point. This allows trains to safely use platforms that are shorter than the train length. |
