Google doesn't support the [linked trips](https://gtfs.org/schedule/reference/#linked-trips) feature through `transfer_type` values of `4` or `5`.\n\nBlock transfer, also called in-seat transfer, is available when a set of\ntrips meets the following conditions:\n\n1. The trips are consecutive.\n2. The same vehicle operates both trips.\n3. The trips are provisioned with the same `block_id` value in the `trips.txt` file in the transit feed.\n\nPrerequisites\n-------------\n\nFor Google Maps to recognize that block transfers between trips are\npossible, the following prerequisites must be met:\n\n1. The trips must use the same `block_id` value in `trips.txt`. This indicates that the trips use the same vehicle.\n2. The trips must operate on the same days, or on consecutive days if a trip crosses midnight.\n3. The trips must be consecutive and not overlap.\n4. The last stop of the arriving trip and the first stop of the departing trip must either be the same (recommended) or physically close.\n\nUse `block_id` to enable block transfers\n----------------------------------------\n\nBlock transfers can be made between consecutive trips on different routes or on\nthe same route if the route is a loop line. Use the `block_id` field to specify\nwhich trips are in one block and where in-seat transfers are an available\noption.\n\n### Example 1: Block transfers for scheduled trips\n\nIn this example, consider the following values in each file:\n\n`trips.txt`\n\n| `route_id` | `trip_id` | `block_id` |\n|------------|---------------|------------|\n| `RouteA` | `RouteATrip1` | `Block1` |\n| `RouteB` | `RouteBTrip1` | `Block1` |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\n`stop_times.txt`\n\n| `trip_id` | `arrival_time` | `departure_time` | `stop_id` | `stop_sequence` |\n|---------------|----------------|------------------|-----------|-----------------|\n| `RouteATrip1` | `12:00:00` | `12:01:00` | `A` | `1` |\n| `RouteATrip1` | `12:05:00` | `12:06:00` | `B` | `2` |\n| `RouteATrip1` | `12:15:00` | | `C` | `3` |\n| `RouteBTrip1` | | `12:18:00` | `C` | `1` |\n| `RouteBTrip1` | `12:22:00` | `12:23:00` | `D` | `2` |\n| `RouteBTrip1` | `12:30:00` | | `E` | `3` |\n\n\u003cbr /\u003e\n\nIn this example:\n\n- A user who searches for a route from stop A to stop E is directed to embark at stop A at 12:00 on Route A and to stay on the vehicle when it reaches stop C after the end of `RouteATrip1`. This is because the same vehicle services `RouteBTrip1` for Route B.\n- Passengers on `RouteATrip1` who want to continue on to a stop on `RouteBTrip1` can stay on the vehicle for this transfer.\n- Passengers of other trips on other vehicles along these same routes don't have this option because they use different vehicles for each trip.\n\n### Example 2: Block transfers for frequency-based trips with exact times\n\nBlock transfers are supported only for frequency-based trips that meet one of\nthe following conditions, in addition to the requirements listed in the\n[Prerequisites](#prerequisites) section:\n\n- If the trip is a loop, it must start and end at the same stop.\n- In `frequencies.txt`, the value of the `exact_times` field must be `1`.\n\nThe following example describes how to set the values for the second condition:\n\n`trips.txt`\n\n| `route_id` | `trip_id` | `block_id` |\n|------------|----------------|------------|\n| `route1` | `route1_trip1` | `block_2` |\n| `route2` | `route2_trip1` | `block_2` |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\n`stop_times.txt`\n\n| `trip_id` | `arrival_time` | `departure_time` | `stop_id` | `stop_sequence` |\n|----------------|----------------|------------------|-----------|-----------------|\n| `route1_trip1` | `08:00:00` | `08:04:00` | `stop1` | `1` |\n| `route1_trip1` | `08:10:00` | `08:14:00` | `stop2` | `2` |\n| `route1_trip1` | `08:20:00` | | `stop3` | `3` |\n| `route2_trip1` | | `08:24:00` | `stop3` | `1` |\n| `route2_trip1` | `08:30:00` | `08:34:00` | `stop4` | `2` |\n| `route2_trip1` | `08:40:00` | `08:44:00` | `stop5` | `3` |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\n`frequencies.txt`\n\n| `trip_id` | `start_time` | `end_time` | `headway_secs` | `exact_times` |\n|----------------|--------------|------------|----------------|---------------|\n| `route1_trip1` | `08:00:00` | `08:20:00` | `600` | `1` |\n| `route2_trip1` | `08:24:00` | `08:44:00` | `600` | `1` |\n\n\u003cbr /\u003e\n\nIn this example:\n\n- A user who searches for a route from `stop1` to `stop5` is directed to embark at `stop1` at 08:00 on `route1`. The user then stays on the vehicle when it reaches `stop3` after the end of `route1_trip1`. This is because the same vehicle services `route2_trip1` for `route2`.\n- Passengers on `route1_trip1` who want to continue on to a stop on `route2_trip1` can stay on the vehicle for this transfer.\n- Passengers of other trips on other vehicles along these same routes don't have this option because they use different vehicles for each trip.\n- Take `route1_trip1` for example. The value of `headway_secs` is half the interval between `start_time` and `end_time`. In this case, it means there are two trips. To learn more about the usage of `headway_secs`, refer to the [GTFS Schedule Reference on\n gtfs.org](https://gtfs.org/schedule/reference/#frequenciestxt).\n\nBlock transfer in a loop line\n-----------------------------\n\nIn a loop line, the first stop and the last stop of a trip are the same and have\nthe same `stop_id`. This is required for both schedule-based and frequency-based\ntrips.\n\nProvided that consecutive loop trips have the same `block_id`, block or in-seat\ntransfer is enabled, which lets passengers of the first trip remain on the\nvehicle when it continues on the next loop.\n\nValid blocks in GTFS feeds\n--------------------------\n\nFor block transfer to be possible, you must properly define one or more blocks\nin the feed. To pass validation, trips that belong to the same block can't\noverlap and must have the same `route_type` (subway, rail, bus, and so forth).\nTrips can belong to the same block even if they're on different days. If any\nblocks are defined in a static feed, they show in the Validation Report, on the\n**Overview** tab.\n| **Note:** The feed validator only checks the integrity of the feed. It doesn't check for any of the other conditions that make block transfer possible."]]
