We have been investing in mid-train remote distributive locomotives for the last many years, as have my friends at CP. The ability to place that air compressor in the middle of a train allows you to continue to run the same length you run all year round.
On top of that, what we've built in-house over the last few years are air compressor boxcars, and we're going to increase that fleet by 50%. Incrementally over the last few years, we've really focused on ways to reduce the number of issues we have due to air compaction, as you say.
