Why #

CBTC is a tiny niche, tinier still on Bluesky. I figured it would be nice to have a feed to find conversations about communications based train control and other modern signaling systems. You can view it, or add it to your feeds here.

How it works #

I run a modified version of the Bluesky feed generator Python starter (link). You can see the feed, or add it to your feeds here.

Keywords #

The feed picks up posts using the following keywords.

• CBTC/communications based train control
• Trainguard (Siemens offerings)
• Seltrac/ICTS/Intermediate Capacity Transit System (UTDC/Thales/Hitachi lineage)
• NOVA Pro/Stadler NOVA (Stadler offering)
• 4LM/TBTC/transmission based train control (TfL)
• GoA1/GoA2/GoA3/GoA4/Grade of Automation
• Urbalis/Fluence/Cityflo (Alstom offerings)
• OCTYS/OURAGAN/SAET/NExTEO/SACEM (systems in Paris)
• OPTIO (CAF offering)
• IEEE 1474/EN50126/IEC62290 (CBTC standards)
• VOBC/VCC/zone controller (system components)
• Muni ATC (Muni Metro’s name for CBTC)
• Automatic Train Control, Automatic Train Protection

The system is not case-sensitive. Because it is a very simple system, it may misidentify posts on occasion, though measures have been taken to avoid this.
