Yes and no. Subways are electric, therefore they can be ran off of alternative energy, which obviously makes them more sustainable than heavy rail diesel trains. However, electric light rail trains that are above ground would probably be greener because you don’t have the environmental burden of burrowing and building a train system underground.
