Classification Locomotive Control for Automated Yard Car Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of sorting and assembling train cars in classification yards is traditionally manual and labor-intensive, requiring skilled operators to control locomotives, which can be dangerous and prone to human error.
Innovation Solution
An automated classification system that generates control commands for classification locomotives based on train car and track information, enabling autonomous or semi-autonomous movement of train cars to designated tracks, using a graphical user interface and a controller communicatively coupled to the locomotive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used for train car classification, then experienced operators can control locomotives to sort train cars, but the process is dangerous and prone to human error
Solution Approach 1:
The patent replaces the manual mechanical control system with an automated computer-based control system. The controller receives information about train cars and classification tracks, generates control commands autonomously, and transmits them to the locomotive, eliminating the need for human operators to physically control the locomotive and thereby removing safety risks associated with manual operation.
Solution Approach 2:
The classification system performs classification operations autonomously without human intervention. The controller automatically processes train car information, determines optimal classification tracks, generates control commands, and executes the classification process, allowing the system to serve itself and eliminate human error and safety concerns.
2Productivity
If manual operation is used for train car classification, then skilled operators can manage the process, but it requires well-trained and experienced human train operators
Solution Approach 1:
The patent substitutes the human operator's cognitive and decision-making functions with an automated control system. The controller automatically processes train car information, determines classification tracks based on destination data, and generates control commands, thereby eliminating the need for skilled operators and their extensive training while maintaining or improving classification efficiency.
Solution Approach 2:
The system performs all classification decision-making and execution autonomously. The controller self-manages the entire classification process by receiving train car information, determining optimal tracks, generating commands, and coordinating locomotive movements without human intervention, thus eliminating training requirements while maintaining productivity.
3Ease of operation
If automated control commands are generated for classification locomotives, then less experienced operators can manage train car sorting, but the system requires a controller communicatively coupled to the locomotive
Solution Approach 1:
The patent replaces complex manual operational skills with a standardized automated control system. The controller automatically generates control commands based on train car information and track data, transmitting them to the locomotive via communication interfaces. This substitution allows less experienced operators to manage classification effectively while the control system infrastructure handles the complexity of precise locomotive control.

AI summary
In one instance, disclosed herein is a method for automating a train car classification process, including: receiving information indicating at least one train car within a classification yard and a classification track within the classification yard; generating, based at least in part on the at least one train car and the classification track, at least one classification control command for a classification locomotive within the classification yard; and providing the at least one classification control command to the classification locomotive for execution, wherein execution of the at least one classification control command by the classification locomotive causes the classification locomotive to move the at least one train car to the classification track.
