There are other people on this board who post for its own sake - just to create threads consisting mostly of drivel. You are capable of better.The article describes the use of CBTC to replace the signal room equipment at Chambers Street. It turns a fire-related loss into an opportunity to deploy and test CBTC. The article says that that identification blocks will be created at Chsambers of 600' length. It does not say that this is what will be happening on the Canarsie Line. It sounds like the TA is using this opportunity to check CBTC equipment on a relatively small stretch of track (1/4 mile, which is going to be all of two "blocks") while keeping the overall procedure the same as the train leaves the little CBTC territory and renters fixed block territory. This will not hurt capacity, because trains are 600' in length and one caould always arrange "key-by" procedures anyway. Your past several posts have shown: 1) You have a good theoretical grasp of CBTC operation and its putative components, and how those components work together to provide operational capability which can replace fixed signaling. And you explain this clearly simply and logically. 2) You explained the difference between inductive loop and RF applicatuions very well, enough to help me (I am not an engineer) understand it. But: 2) You have no idea how or why siemens approach to NYC's problem is different (or what is being solved) in comparison to other similar instalations. 3) You have no idea how an R143 will interface with the CBTC on the Canarsie Line, though you're doing your best to wing it. 4) You criticize NYCTA for its management and implementation of CBTC without knowing exactly what's entailed. Italso begs the question: Let's see you do it. If we appointed you chief CBTC manager tomorrow, I'd expect NYCT's chief engineer to be helping you wipe the egg off your face. That might be your best and only achievement. |
