The point of mass transit systems isn't to get you to the exact place you want to be, it's to get you close enough to it or be able to give you another form of public transport to get there.
In cities with good systems, the train will have a connection to a bus or something that will get you to the golf course. They won't store your clubs, but golf courses have storage where you can leave the clubs.
People that live in cities where most of the population rely on public transport will do what's needed to make things work.
