Planning transit service or evaluating peak-period crowding? This calculator totals a train's full passenger capacity, seated and standing.
Total Capacity = (Seats Per Car + Standing Capacity Per Car) x Number of Cars
Example
8 cars, 60 seats and 40 standing spaces per car:
Total Seated = 480, Total Standing = 320 → 800 total capacity
Why Standing Capacity Varies So Much by Service Type
Standing capacity is commonly included in urban and commuter rail capacity figures during peak periods, reflecting real-world crush-load conditions during rush hour - long-distance and high-speed intercity services, by contrast, typically operate on a seated-only basis with little to no standing capacity counted, since passengers expect a seat for longer journeys.
Peak vs. Off-Peak Capacity Planning
Transit agencies commonly plan around this full standing+seated capacity figure for peak-hour service, while evaluating off-peak or overnight service against seated-only capacity, since standing for a shorter, less-crowded off-peak trip is a very different rider experience than standing during rush hour.
