What they're saying is that there will be just as many cars on the road as before and therefore not reducing the environmental impact of the road.
I imagined it to be something like this:
Old:
- Road: 1000 users
- Train tunnel: 1000 users
New:
- Road: 1000 users
- Train: 2000 users
Although the train is more environmentally friendly than the road, I think the article is saying the impact of adding it is just that more people make the trip rather than the same number of people doing it in a more environmentally friendly way. This is basically the concept of induced demand i.e. build it and they will come.
