There are countless examples of short-line railroads and Class Is working collaboratively to better serve customers in addition to boosting their top lines. We detailed one such example in an article that was published in our September issue. In June, the Louisville & Indiana Railroad Co. (LIRC) and interchange partner CSX Transportation filed a request with the Surface Transportation Board (STB) for approval of an easement and joint-use agreement under which CSX would increase the number of trains it runs on the short line's track and invest $70 million to $90 million in infrastructure upgrades. As part of the pact, the LIRC would sell an easement to CSX for $10 million. If approved, the agreement would provide CSX more capacity to improve service for its customers in the Indianapolis-Cincinnati-Louisville area. And it would help the 106-mile LIRC better serve existing customers and attract new ones.The railroads hope to receive STB approval by year's end, as freelance writer Kathy Bergstrom reports. For more details — and for more on the upgrade work the LIRC has been doing (most notably with its locomotive fleet) to prepare for the growth to come, check out the rest of the story.
