Where to switch trains.

Example of how to debug this kind of issue using log.Infof to print the status
of the BFS function as it traverses the graph.
You can start up the app directly via dev_appserver.py and issue requests via
web browser and watch the real requests. but the "real" train network data is
complex, so it's easier to run smaller tests, and that's what app_test.go
does. You can run it via
go test *.go
You'll only see logs if one of the tests fails (and currently one of them will). But if you'd like to see logs even when the tests are passing, you can run:
go test -v *.go
