Is it true that underground subway and train tunnels get mobile phone coverage through distributed antenna systems or leaky feeder cable installed along the tunnel?

Yes. A reference article on leaky feeder systems states that a leaky feeder cable run along tunnels provides underground mobile communication in mass transit railways, and that a Distributed Antenna System is an alternative deployed in New York City Subway stations for mobile and Wi-Fi coverage.
