Step-by-Step Guide: Navigating Union to Scarborough GO

Executing a seamless journey from Downtown Toronto to Scarborough GO requires understanding terminal layouts and payment validation rules.

1. Navigating Union Station Departure Concourses

GO Transit departures operate out of three primary concourses inside Union Station:

• Bay Concourse: Offers direct access to tracks 4 through 13. Ideal for Lakeshore East boarding.
• York Concourse: Provides western platform access and connects directly to the TTC Union Subway Station.
• VIA Rail Concourse: Situated centrally; caters primarily to intercity passenger rail but offers pass-through access.

Check the large electronic departure screens throughout the concourse for the Lakeshore East destination (trains bound for Oshawa or Durham Region) and note the assigned platform number.

2. Validating Payment (Tap-On Protocol)

Before ascending the stairs or elevators to the train platform:

• Tap your PRESTO card, credit card, or debit card on the green GO fare validator devices located at concourse entrances or platform bases.
• Ensure the screen displays a green checkmark and confirmation chime.
• If using a digital ticket purchased online, activate the ticket on your smartphone at least 5 minutes prior to boarding.

3. Boarding the Train

• Board through any door on the green and white double-decker train cars.
• Accessibility Cars: The middle coach of every GO train is the accessible car, featuring automated ramps and level boarding.
• Quiet Zone: The upper level of all GO train coaches during weekday morning and evening peak hours is designated as a Quiet Zone. Passengers are expected to keep conversation quiet and use headphones at low volume.

4. In-Transit Experience

The train travels east out of Union, passing through the Don Valley rail corridor, stopping briefly at Danforth GO Station (approx. 10 minutes from Union), and continuing east toward Scarborough.

5. Arrival and Tap-Off at Scarborough GO

• Upon arrival at Scarborough GO Station, alight onto the platform.
• Locate the green GO fare validator readers at the platform exits or pedestrian tunnels.
