In May 2019, the first-ever propane unit train from the Bakken to Mexico reached its destination, and since then, three more of these 100-car, single-commodity “bulk” trains have made the same trip. Facilitating these shipments by Twin Eagle Liquids Marketing is Marathon Petroleum Corp.’s (MPC) unit train-loading terminal in Fryburg, ND, which was initially set up to load crude oil but was recently expanded to handle propane too. And soon, the terminal in Torreón, Mexico, that has been receiving these unit trains will have a new loop track too, enabling producers and marketers to take full advantage of the bulk transport option. Today, we look at the economics and challenges of this relatively new propane export route.

In May 2019, Twin Eagle Liquids Marketing shipped a 100-car train filled with propane from North Dakota to Mexico, marking the first-ever single-commodity train — i.e. “unit train” — between the Bakken and the U.S.’s southern neighbor. As it turns out, it was also the first of what appears to be a regularly scheduled run to Mexico. Since May, three more unit trains have made the journey south from the Bakken’s first unit train terminal for propane. Rail shipments of propane to Mexico as part of mixed-goods trains aren’t new, but figuring out how to economically ship large quantities of propane via unit trains has long evaded NGL marketers and producers — that is, until now. What are the economics and other factors that finally made it possible, and what are the prospects and challenges ahead for unit-train exports to Mexico? Today, we look at how the first all-propane train to Mexico came to pass and what the outlook might be for these shipments to continue.
