The Freight Transportation Services Index (TSI), rose 0.4% in September from August, rising for the second consecutive month, according to the U.S. Department of Transportation Bureau of Transportation Statistics (BTS).

From September 2025 to September 2026 the index fell 1.5%. The Freight TSI measures the amount of freight carried by the for-hire transportation industry.

The Freight TSI increased in September due to increases in rail intermodal, trucking, and water; air freight and rail carloads decreased; while pipeline volumes remained unchanged.

The freight transportation index consists of:
� For-hire trucking,
� Railroad freight services (including rail based intermodal shipments such as containers on flat cars),
� Inland waterways transportation,
� Pipeline transportation (including principally petroleum and petroleum products and natural gas), and
� Air freight.
