# Inland Rail (IPI) Delays and Rising Detention Risk Through Peak Season

 July 22, 2026

Record US container imports this month are clearing the ports smoothly but choking the inland rail network. If you move ocean freight IPI through Chicago or the Midwest, this is already adding cost and transit time to your cargo, and it will stay with us through the summer. The ports themselves are flowing well. The problem has moved inland, to the rail ramps and the drayage leg.

Here is the plain version of what is happening and what we recommend.

## What is driving this

- US container imports are hitting an all-time record this month. Major ports are forecast to move 2.47 million TEU in July, topping the previous monthly record set in May 2022. This is a frontload rush ahead of the Section 122 surcharge cap on July 24 and the Section 301 tariff structure that follows in August. Every box importers can land before the deadline, they are landing now.
- The surge is clearing the docks but choking the inland network. There is almost no vessel backup at Los Angeles and Long Beach. The congestion is at the rail hubs and on the roads out of them.
- Chicago is the pressure point. The I-294 / I-290 / I-88 interchange is now rated the number one freight bottleneck in the country, with rush-hour truck speeds around 33 mph. The interchange rebuild runs through the end of 2027, so this is a structural condition, not a passing snarl.
- Both BNSF and Union Pacific are managing volume with metering and surcharges. Union Pacific has placed California, Chicago, and Laredo under a constrained-market designation that limits daily equipment access, and has extended peak-season surcharges to shippers exceeding weekly allotments.

## Impact to your shipments

- A rail-to-road handoff that normally takes 24 to 48 hours is running several days, and in the worst Chicago cases containers are sitting up to ten days waiting on a chassis or a truck window.
- You have two cost clocks running at once, and they run independently. Rail free time is roughly half of ocean free time, often only one to three days, and it starts when the railroad notifies that the box is grounded, not when the train arrives or when you notice it is available. Meanwhile the ocean carrier keeps charging per diem on the container until it comes back empty, and that clock does not pause because the box is stuck at a congested ramp.
- Chassis splits of around $250 each, missed terminal windows, and detention stack on top. On a bad Chicago move these are not edge cases, they are the base case right now.

## What Transmodal is doing

- Dispatching drayage against the railroad grounding notification, not the train arrival, so a truck is ready the moment your box is available.
- Watching rail free-time and per diem clocks on your active inland shipments and flagging any box approaching a charge before it hits.
- Pricing coastal transload plus domestic truck as an alternative on time-sensitive Midwest freight, where the fast IPI route has become the slower and more expensive one.
- Building realistic current transit times into every new Midwest quote. If your delivery estimates are still based on last year's rail performance, they are wrong, and we would rather correct them now than surprise you at delivery.

## What we recommend from you

- Confirm receiving capacity and unload appointments early, and return chassis promptly. The single biggest driver of avoidable cost right now is boxes and chassis sitting after they ground.
- For any inland shipment with a fixed delivery or production date, tell us now so we can evaluate transload versus IPI before the cargo lands.
- Approve a per-container buffer in your landed-cost model for potential rail storage and chassis fees on Chicago and Midwest moves through peak.

## Timeline

Expect these conditions through August. Import volume is forecast to fall back below normal levels from late August into the fall as the pre-tariff rush unwinds, which should ease equipment pressure. The Chicago interchange itself stays constrained into 2027. We will update this advisory if metering or surcharge terms change materially.

Your account representative is on top of your specific shipments and can walk through options on any box. Reach out any time.
