It's 2 hours times the number of passages through the tunnel. Hint: there will be more than a single passage.
Jokes aside, there are sometimes rail projects where millions are spent to save 2 minutes. Or even just tens of seconds. Over the lifetime of the infrastructure it is still worth it, especially when combining multiple projects.
2 hours savings is huge. You won't find many infra projects with those kind of time savings.
