This type of coach is also used by a number of other commuter railways across North America. They have a seating capacity of 162 and a standing capacity of 248 per coach, or 5,256 per train (maximum crush load).

In 2026, the capacity of a standard GO Transit train depends on the number of coaches, which typically ranges from 10 to 12. Most GO trains utilize the Bombardier/Alstom BiLevel coach, which has a distinctive octagonal profile designed to maximize space. A single "Standard" coach can hold approximately 162 seated passengers, but when including standing room, its total capacity can swell to over 360 people during peak hours. A full 12-car train, which is the current standard for the busiest lines like Lakeshore West and East, can therefore transport nearly 2,000 seated passengers and a total "crush capacity" of over 4,300 people. The newer "Cab Cars" (the cars at the end with the engineer's cabin) have slightly fewer seats due to the control equipment, but they still maintain a massive volume compared to traditional single-level commuter trains used in other cities.
