Railroad Park is a couple of blocks of green space in downtown Birmingham, Alabama.

You could hear cicadas in the trees.

There are turtles swimming in the

pond. And just on the other side of the fence, there are train tracks. And these train tracks

could be on their way to making history, along with tracks in San Francisco, Chicago, Phoenix, and

Savannah. They could all be connected in the country's first coast-to-coast

railroad. Now, that is all assuming a planned merger between some of the country's

biggest railroad companies actually happens. And we're talking freight trains here, not

people trains. And there is a line of shippers and unions who are against this merger ever leaving the station.

This is the indicator for Planet Money.

I'm Adrian Ma.

And we're here with friend of the show, Stephen Besaha, from the Gulf States Newsroom.

Thanks, Stephen, for bringing us this story.

Happy to deliver.

And on today's show, we take a whistle-stop tour into the world of mergers.

We find out how this can fast-track shipping, inspect the rough track record of past railroad mergers,

and learn why both unions and shippers want this latest plan derailed.

Stephen, do you have any more train puns you want to work out of your system?

Let's just try to stay on track and keep chugging along.

That's the ticket.

All aboard!
