A reader asked me to include the Dow Jones Transportation Index in my analysis of bear markets. That led me to Bureau of Transportation (BTS) data that I had not investigated before.

Here are some charts I created from data downloads plus an additional chart from Fred. The BTS most recent data is for October.

Truck Tonnage Index

The index made a new record high of 118 in October.

Seasonally-adjusted rail freight carloads - U.S. Department of Transportation, Bureau of Transportation Statistics (BTS) calculation from data collected by Association of American Railroads.

The monthly rail carloads and intermodals are estimated by dividing the weekly sum by 7 (7 days in a week) and then summing for the number of days in the month (31 days for May, 30 days for June, etc.).

Intermodal freight transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation (e.g., rail, ship, and truck), without any handling of the freight itself when changing modes.

Seasonally-adjusted, intermodal traffic peaked in July of 2018. Unadjusted traffic peaked in October.

The above chart suggests decreasing dependence on rail coupled with an increasing number of intermodal shifts to some other form of transportation, most likely trucks.

Humming Along

The BTS data makes you think the economy is humming on all four cylinders. The DOW transportation index is another matter indeed.

The November and December BTS data might be interesting.
