In plain English
It is a time limit for changing from one transport service to another during one trip. That interval starts when one service arrives and ends when the next one leaves, and the fare or ticket uses it to decide whether the change still counts as part of the same journey.
In context
Here, "transfer window" labels the amount of time the fare rules allow for a change from one service to another to remain within the same journey.
- Situation
- Using rail, bus, metro, ride, and local-transit tickets and service updates
- What it communicates
- labels the permitted changeover period in the fare rules.
Meaning limits
The term itself does not tell you the actual length of that period.
Examples
“Under the ticket rules, the bus arrived at 8:10, and the 8:25 tram still counted as part of the same journey because it left within the transfer window.”
“The day pass includes a 30-minute transfer window between the ferry and the bus.”
