I don't know about leaky antenna solution, but I know that coaxial cable runs through NYC subway for push to talk communication. It may be adopted for such a service. If base stations are put in the tunnel, first where would you put it? I strongly believe it's not going to work well. In rush hour, people are literally packed, human body is conductive, signal will lose its strength fast going through. Consider a 30 miles/hour train passing under a transmitter in a narrow tunnel, think about your coverage, how far apart you are going to put the base stations?
If micro transmitters are placed inside the cars, that's possible, then all cars should be wired. As for health concern, I exagerrated. Although lots of research done but nothing conclusive found in 15 years, there will be people objecting to it seriously. Signal fades exponentially, a cell phone next to your ear is a greater radiation source. Any infrastructure setup should follow the recommendations/guidelines for radiation exposure limits.
