General Motors, audited.
36 of ~61 facilities (US scope)1,687 dock doors3,370 trailer spots21 rail-served
We core-sampled 36 of ~61 plants, The audited sites cover GM's freight-relevant US assembly, powertrain, stamping, casting, battery, and parts-distribution facilities, representative of the 61-site current-operations network.
Network size: GM US Operations: 12 vehicle assembly plants + 24 stamping, propulsion, component and battery plants + 25 parts distribution centers = 61 freight-relevant US facilities (the 2 engineering campuses are R&D, not freight; divested/idled plants excluded). https://www.gm.com/company/us-operations (2026-06-19)
Public audit. Not affiliated with General Motors. Data from satellite imagery + public records.
We audited General Motors’s yards from satellite.
Click any site for its gate, docks, and drop yards. No badge, no NDA, just what a driver sees.
General Motors’s stack is connected. The yards never were.
Your TMS runs the road. Your WMS runs the building. The yards are the tier between them, and they were never on the network.
Every truck gets re-keyed, re-queued, and re-found at each step. The lost time lives between the steps, which is why no single tool ever fixed it. The audit below is that gap, measured on your real yards.
A real audited site, played gate→dock→exit on the true yard geometry. Switch sites with the picker.
GM CCA - Memphis Processing Center, Memphis TN
No guard. Driver finds the call box, hits the buzzer, waits for someone inside to respond.
Movement durations are honest floors set by yard geometry; the uplift lands on the wait fields (queue + dispatch + secondary checkpoints). “Today” timings reflect the radios-and-clipboards world; “With YardFlow” reflects the protocol acting end-to-end. We may be wrong about parts of this, your actual numbers will tell us where.
What the handoffs cost across your network, and what removing them is worth
Read from satellite + Street View across all 36 facilities. At a comparable network, Primo Brands cut drop-and-hook turns from ~48 to ~24 min. Set your real volumes and margins in the calculator to put a number on it.
What surprised us reading General Motors’s network
Three patterns held across the sites we sampled. None of them show up on a facility list. All of them change how the yard runs.
- 01
21 of 36 audited GM sites are rail-served. The inbound moves on railcars, and every railcar still ends at a truck gate the network cannot see.
- 02
3,370 trailer spots sit across the 36 yards we audited. That is the parking lot GM's network runs blind on today.
- 03
GM's parts network shows up as 12 processing and distribution hubs in the audited set. Davison Road alone runs 84 docks behind a 132-foot automated tower.
Turn what you saw into a number for finance
This audit is the evidence. The model is the math. Open the calculator seeded with General Motors’s audited yards, set your real volumes and margins, and it sizes the opportunity to the dollar.
This deep-dive is the evidence behind the /for/general-motors memo.

We are not asking for a pilot. We are asking for a conversation.
A 30-minute call, direct with Casey. We show you what we found across your yards, you tell us straight where it fits and where it does not. If the call goes well, we talk pilot. If not, you keep the analysis.
None of these times work? Email me at casey@freightroll.com or call or text me at 410-236-7434, and we’ll find one.
