Triple 14 — Saturday, September 12, 2026

TL;DR — the day in port + freight.

No verified port-level operating data cleared the wire this cycle: there are no dwell times, anchorage or berth counts, chassis-pool utilization figures, or vessel schedule-reliability numbers for LA/LB, NY/NJ, Savannah, or Houston in today's sourced set, so this brief reports the landside picture and flags the quayside gap rather than filling it. What is confirmed is that the inland network is running hot into peak: US rail traffic for the week ending September 5, 2026 totaled 533,545 carloads and intermodal units, up 13.8% year over year, with intermodal alone at 299,148 units, up 18.0% [1]. Read that as a ramp-capacity story, not a vessel-arrival story — the binding constraint on transload and inland moves this month is more likely to be intermodal throughput and equipment turns than berth availability.

Port snapshot — dwell, backups, chassis at LA/LB, NY/NJ, Savannah, Houston.

No verified terminal dwell, truck turn time, chassis availability, or berth-wait data for any of the four ports appears in the fetched sources this cycle. The only directional support is headline-level: Logistics Management's September 10 index carries "August volumes cap best three-month volume run on record for the Port of Los Angeles" and "U.S. container imports hit third-highest level on record in August, reports Descartes" [2], and AJOT's week-35 traffic page links "Port of Long Beach reports best August on record" [1] — enough to establish record-adjacent August import volume across San Pedro Bay, not enough to state a dwell hour or a chassis street-dwell figure. Nothing at all on NY/NJ, Savannah, or Houston. For today's operating decisions, pull numbers at the primary source — POLA Signal / Port Optimizer, PANYNJ terminal advisories, GPA operations updates, Port Houston terminal notices — and do not price drayage off secondhand congestion talk.

Service advisories — weather, labor, rail connections.

No current weather or labor advisory affecting berth or gate throughput at the four ports appears in the fetched sources; treat the absence as a gap in coverage, not as an all-clear, and confirm against NWS marine products and ILA/ILWU notices before committing appointments. On rail connections, the signal is volume, not disruption: week 35 carloads were 234,397, up 8.9%, with nine of ten commodity groups gaining and coal the lone decliner at 58,037 carloads, down 3,547 [1]. Year-to-date through 35 weeks, US volume stands at 17,890,653 carloads and intermodal units, up 3.6% [1], confirmed independently by Progressive Railroading on September 10 alongside Canadian volume of 5,759,324 units, up 1.5%, and Mexican volume of 890,474 units, up 7.7% [3]. August was a record intermodal month at nearly 297,000 containers and trailers per week on average, up 4.4% annually and ahead of June 2026 — the seventh straight August gain [2]. Record ramp throughput is consistent with tighter equipment turns at port-adjacent yards, so build slack into dray appointments even where terminal gates are clean. One caution on older material in circulation: the available weather-and-rail briefing describing Chicago as North America's primary bottleneck, where high volumes magnify single-event delays, is dated February 20, 2026 and is a winter-pattern piece [4]. The structural point about Chicago holds; nothing in it describes conditions today and it should not be passed to customers as an active alert.

Regulatory — port authority rulings, demurrage rules, tariffs.

No FMC demurrage/detention action or port authority tariff ruling appears in the fetched sources this cycle. On trade policy, Canada has matched new US tariffs dollar for dollar as talks stall, following US implementation of additional 50% tariffs on certain Canadian goods under Section 338 [2]. Cross-border volume is already reflecting the friction unevenly: Mexican carloads fell 7.4% in week 35 while Mexican intermodal rose 10.1% [1]. Shippers with Canadian-origin or Canadian-destined freight should re-verify landed cost assumptions on bookings made before the matching measures took effect.

Signals worth watching — what to track next.

Cost is moving against the buyer on two fronts. The national diesel average hit an all-time high for the week of September 7 per EIA, and Port Tracker projects that September could pace all 2026 US-bound import volumes [2] — peak demand into record fuel argues for pre-booking drayage and intermodal capacity now rather than spot-buying into the back half of the month. For a leading read on the port-adjacent congestion this brief cannot yet quantify, track weekly Class I terminal dwell, average train speed, and cars online from the STB filings; ramp dwell deteriorating at Chicago, Memphis, or the LA basin yards will show up there before it shows up in a terminal advisory. The items to chase before the next cycle: terminal dwell and truck turn times by port, chassis pool utilization, anchorage and berth-wait counts, ILA/ILWU labor notices, and NWS marine or tropical advisories for the Gulf and South Atlantic.
