Jan 5, 2026

Phase 1: Downtown Core Development Begins

We're focusing on the TTC Streetcar network, specifically Routes 509 (Harbourfront) and 510 (Spadina). These routes form the backbone of waterfront transit and will serve as the foundation for the entire GTAT project.

Technical Highlights:

  • Track Geometry: Built to TTC broad-gauge (1495 mm)
  • Data-Driven: Using real TTC references and topographic data
  • Custom stations: Union, Queens Quay, Exhibition Loop

TTC Flexity Outlook: Modeling Progress

The workhorse of downtown Toronto is coming to life in Blender. We're meticulously recreating the Flexity Outlook with accurate interior layouts and door configurations.

Current Focus:

  • Exterior modeling with accurate dimensions
  • Low-floor interior layout matching TTC specifications
  • Realistic driving physics and motor sounds

Custom Passenger Information System (PIS)

We're developing a custom PIS system to replicate the real-world dynamic text and announcement patterns used by the TTC. This includes the iconic 'ding-dong' door chimes and automated stop announcements.

Features in Testing:

  • Authentic TTC announcement voices
  • Dynamic route and destination displays
  • Real door chime sounds and motor hums

About The Project

The Vision 🏙️

The Greater Toronto Area Transit project is a large-scale, high-fidelity recreation of the transit networks across Toronto and the GTA. Our focus is on 100% authenticity, preserving the unique character of Ontario's public transportation—from the hum of the Flexity motors to the specific "ding-dong" of the door chimes.

We aren't just building tracks; we are recreating the atmosphere of the city—the sounds, the specific architecture, and the unique operating challenges.

Our Commitment to Realism

We use real topographic data, OpenStreetMap references, and on-site research. Key features include the unique TTC broad gauge (1495 mm), authentic stop spacing, and functional Passenger Information Systems (PIS).

The Map & Vehicles

Current Focus: Phase 1 – Downtown Core

We are currently concentrating on the TTC Streetcar network along the waterfront, building the foundation that will support the entire GTA transit ecosystem.

Community & Contact

Get Involved 💬

GTAT is currently a solo development effort by Timm (DevTimmOfTO), but the vision is too big for one person. This is a passion project built for the community, and we're actively looking for collaborators.

We Need Help With:

🎨 3D Modelling (Blender) - Buildings & Infrastructure
💻 LOTUS Scripting (Pascal) - Vehicles & Signals
🔊 Sound Design - Real TTC/GO recordings
🖼️ Texture Artists - Realistic Toronto signage

Can You Help? We're Looking For:

  • 📷 Reference photos of Toronto infrastructure and intersections
  • 🎵 TTC/GO sound recordings (motors, announcements, door chimes)
  • 📐 CAD data or technical drawings for rails and stops
  • 🗺️ Local knowledge and operational details
