A system for improved intermodal freight transportation is described herein. Improved carriages and support trusses are provided that beneficially move the load-bearing structure to interconnected support trusses forming a top-end spine of the train with freight containers equipped with wheels hanging underneath. Upon entering a terminal, the floor adjacent to the rails may be configured to gradually rise until the container's wheels are supporting the container's weight. When properly aligned with a container exchange station, the container's connections to the train may be configured to release the container from the train, and the container's wheels may be configured to pivot, allowing the container to be rolled to the side of the train and replaced by another. This may allow the container to be replaced without having to lift the container or disconnect any of the rolling stock components.

A digital detection method for suspended particulate matter is disclosed and includes following steps: providing a particle sensor (1), wherein the particle sensor (1) includes an airflow channel (11), a miniature pump (12), a laser emitter (13) and a photodiode (PD) (14).
