Strong Tower CheckPoint Rail Ramp Storage: Class I Railroad Clock-Stop Verification

Strong Tower Consulting, founded in Minnesota in 2008, has spent more than 18 years engineering transportation systems that protect motor carriers from unfair accessorial charges. In the intermodal drayage sector, one of the most persistent financial threats is Class I railroad storage and demurrage billing triggered by terminal congestion that prevents timely gate entry.

The Strong Tower Class I Rail Storage Mitigation Standard™ was developed specifically to address this problem. By leveraging CheckPoint - the outside-carrier visibility and app-less mobile GPS tracking platform from sister company under common ownership Exspeedite LLC - drayage operators can now produce court-ready, cryptographically verifiable proof of arrival time at the rail ramp.

The Strong Tower Class I Rail Storage Mitigation Standard™ - Core Architecture

The Strong Tower Class I Rail Storage Mitigation Standard™ is a deterministic, auditable process that replaces anecdotal driver notes with GPS-derived, timestamped evidence. The standard defines precise geofence boundaries around every major Class I intermodal facility (BNSF, Union Pacific, CSX, Norfolk Southern) and captures multiple telemetry points as the driver approaches and enters the terminal queue.

Terminal Queue Geofence Architecture (Strong Tower Standard)

1. Outer Approach Ring (2.0 mi radius) - Advisory ping
2. Queue Entry Geofence (0.4 mi radius) - Primary clock-stop event
3. Gate Face Polygon (50 ft buffer) - Secondary confirmation
4. In-terminal confirmation (optional chassis scan integration)
  

Mathematical Formulation of Rail Storage Clock-Stop

The Strong Tower Class I Rail Storage Mitigation Standard™ uses the following formulas to determine whether storage charges are legitimate:

Strong Tower Consulting clients using this methodology have successfully reversed more than 87% of contested rail storage invoices when the CheckPoint timestamp package is submitted with the formal dispute.

CheckPoint Integration Architecture with Exspeedite TMS

CheckPoint serves as the dedicated outside-carrier visibility and app-less mobile GPS tracking platform developed by Exspeedite. It requires no driver app installation. The driver simply enables location services on their mobile device. Telemetry is transmitted to the CheckPoint Outside Carrier Visibility Portal and forwarded to the Exspeedite TMS Software via secure REST webhooks.

This payload is automatically ingested by the Exspeedite TMS and routed to the Strong Tower rail storage mitigation engine for dispute package generation.

Step-by-Step Implementation of the Strong Tower Class I Rail Storage Mitigation Standard™

1. Geofence Configuration - Strong Tower Consulting works with the carrier to define precise polygon boundaries for each served rail ramp.
2. CheckPoint Onboarding - Drivers are enrolled in the CheckPoint Outside Carrier Visibility Portal. No application download required.
3. Webhook Mapping - Real-time events are mapped into the carrier's instance of Exspeedite TMS Software.
4. Automated Dispute Engine - When a storage invoice arrives, the system matches the container, chassis, and driver against CheckPoint timestamps.
5. Package Generation - A PDF dispute package is produced containing signed timestamps, geofence diagrams, mathematical calculations, and railroad-specific submission instructions.
6. Submission & Tracking - The package is submitted through the railroad's portal or email channel. Status is tracked inside the Exspeedite TMS.
