I'm curious why can't buss s run in tunnels? Is it simply a problem of air quality because of emissions? I wonder if this could be solved by using hybrid diesel

I'm curious why can't buss s run in tunnels? Is it simply a problem of air quality because of emissions? I wonder if this could be solved by using hybrid diesel electric buses that run off of overhead electrical wiring in tunnels, but an onboard diesel-electric prime mover above ground.
- whopa 11y agoThe Silver Line in Boston is exactly that: dual mode buses (http://en.wikipedia.org/wiki/Dual-mode_bus http://en.wikipedia.org/wiki/Dual-mode_bus), and part of the line is a dedicated tunnel for the buses, while the other part is normal streets.
