Posted by Railman718 on Wed Oct 5 00:32:51 2011, in response to Re: CBTC installation begins on the Flushing Line, posted by Stephen Bauman on Tue Oct 4 22:29:26 2011. The design specification for the AWS was 3 tph (20 minute headway). The idea was to permit non-CBTC work equipment to go on the line and still maintain schedules. This spec allows the blocks and the interlocks to coincide.Only reason i can see this if there is some kind of G.O or Major Problem IF a Work train is needed From 8th Ave to Bushwich Aberdeen. All of the automatics are to be removed. As Rob said Only Homesignals will be in Place at Interlockings. AWS is and always Will be in place from Bway Jucntion to Canarise due to Work trains Leaving and going to Linden Yard as well as Lay ups and Wash Trains... The AWS becomes operative, if a train detected on a block does not respond to a radio query. This can happen if foreign equipment is on the track or RF-DCS loses contact with a train. With no knowledge of where all trains are within an AWS block, the only safe operation for CBTC equipped followers is to wait until the AWS block clears. In Laymans terms, If CBTC goes to Chit Between 8th Ave and Bushwick Absolute Block at The Interlockings One train per Interlocking area... |
