This document discusses various modes of transportation used in supply chains including motor/trucking, air, rail, water, pipeline, and intermodal. It outlines the key strengths and weaknesses of each mode such as trucks being accessible but slower than air, rail having low costs but inflexibility, water being best for large volumes over long distances but slower, and intermodal using multiple modes. The document also notes that pricing of transportation is based on handling characteristics, distance, weight, and an inverse relationship with speed of service.
