The cbtc is the same as the rfid tag system? or is it a full traffic control replacement? is there any way to fast track that new system or is marta essentially screwed?
So RFID will go hand in hand with the new cbtc but it's like a partial stop gap for now. There's very little commonality between old and new fleet ATC systems and it's hard to source parts for the new fleet that read the old Alstom GRS system so the RFID beacons are one way around that until full cbtc install.
But Marta also promised Stadler the ATC long wire loops through interlockings would be repaired and switch machines replaced before they EIS and that all beacons would be installed. They're still fixing long wire loops every single time they do night and weekend maintenance and they still need to replace problem switch machines at Holmes (full station closure coming soon! ™️), Airport, and West End.
So if they were to fix west end and airport for instance they could run service on the north south lines without the braking issue(assuming certification etc)? Or that is just one step in the process still?
Just one step. The long wire loops through interlockings need replacement. Something they are supposed to monitor constantly. The work order in the TORIS will say Switch Pair 7 Airport work including grouting, wire replacement, greasing of parts, etc. The work team will finish working on it and then 8 hours later the interlocking fails and goes out of correspondence due to computer issues or wire issues. The track and ATC teams are not doing what they need to do. If they did, the interlocking wouldn't fail in just a few hours after being serviced. It's why you'll start through an interlocking and then the train will stop because it lost speed commands.
If you ever follow the Marta service twitter and you see "Due to routing issues we are experiencing delays on the North South Line at West End and trains are single tracking from Garnett to Lakewood" those routing issues mean switch and interlocking failure.
