It is a bit clearer now

I stopped by the Amtrak station Tuesday afternoon to see what they were doing and discovered that they were again driving pipes into the ground. It appears that they will extend the platform that exists almost the entire way to Cullen street.

Below from a different angle is look at the pipes and the machine that forces them into the ground.

With better weather, they may be able to do this section faster than they did the first section even though this section will be much longer.
