Having more passenger trains on freight train tracks doesn't make much sense, for the reason that you've mentioned. I just don't see, in 50 years, having passenger trains running on diesel between cities and still slowing down freight trains, because the economy is growing.
In any event, with the corridor we're developing we should have dedicated tracks. I have no comment on the specific location, but in general, we should get out of the way and both have our dedicated tracks.
