Frequently Asked Questions

Questions shippers
ask us most.

Straight answers — no jargon, no spin. If you don't see your question here, call us and we'll answer it in minutes.

What is an IMC and how is it different from a freight broker?

+
An Intermodal Marketing Company (IMC) holds direct contracts with Class I railroads — giving us access to railroad-direct rates, equipment, and capacity. A freight broker acts as a middleman, marking up rates they get from carriers or other IMCs. LaserNet Jax is one of only 15 IMCs in the US with direct contracts across every Class I railroad, which means you're getting the best available intermodal rate — not a marked-up version of it.

What lanes qualify for intermodal shipping?

+
Intermodal works best on lanes 750 miles or longer. Below that distance, the drayage costs at each end eat into the savings. The longer the lane, the bigger the advantage. Transcontinental lanes (1,500+ miles) typically see the greatest savings — often 25–30% versus OTR. We'll tell you honestly if your lane qualifies.

What is drayage and how does it work?

+
Drayage is the short-haul trucking that connects your origin to the rail ramp, and the destination ramp to your final delivery point. It's the "first mile and last mile" of an intermodal move. LaserNet Jax coordinates both the origin and destination drayage — we have carrier relationships at every major rail ramp in the country, built over 18+ years. You don't have to find or manage drayage carriers yourself.

How much longer does intermodal take than trucking?

+
Intermodal typically runs 1–2 days longer than OTR on the same lane, factoring in drayage at both ends and rail transit. For most planned freight — inventory replenishment, manufactured goods, retail distribution — that window is completely acceptable. For just-in-time or mission-critical freight, OTR may be the better choice, and we'll tell you that honestly.

What is the East Coast Repositioning Program?

+
This is a special railroad program that moves 40' and 45' containers from East Coast origins to West Coast ramps — Los Angeles, Oakland, Portland, Seattle, and Vancouver BC — at deeply discounted rates. The railroads need to reposition equipment westbound, so they offer exceptional pricing to shippers willing to move freight in that direction. Most shippers have never heard of this program. LaserNet Jax participates directly, and those savings go straight to you.

What types of freight can go intermodal?

+
Any dry van freight that fits in a 40', 45', or 53' container is a candidate — palletized goods, boxed products, manufactured parts, automotive components, agricultural commodities, consumer goods, and retail distribution freight. Intermodal is not suitable for oversized freight, hazardous materials requiring special handling, refrigerated cargo (without specialized equipment), or freight needing flatbed trailers.

What is a rail ramp and why does ramp selection matter?

+
A rail ramp (also called an intermodal terminal) is the facility where containers are loaded onto and off of trains. Ramp selection significantly impacts both cost and transit time. Most providers default to the nearest or most obvious ramp. At LaserNet Jax, we analyze ramp options on every shipment — sometimes routing through a slightly different ramp saves meaningful money or shaves a day off transit. It's a detail most competitors never think about.

Do you handle US–Canada cross-border intermodal?

+
Yes — cross-border intermodal between the US and Canada is one of our specialties. We have direct contracts with both CN Rail and CP Rail, manage customs coordination, and have carrier relationships on both sides of the border. We've done thousands of cross-border moves. The complexity that intimidates other providers is routine for us.
Terminology Reference

Intermodal Glossary

The freight industry loves jargon. Here's a plain-English guide to the terms you'll encounter when shipping intermodal.

Class I Railroad
The largest freight railroads in North America, classified by annual revenue. The seven Class I railroads are BNSF, CSX, Norfolk Southern, Union Pacific, CN, CP, and KCS. LaserNet Jax holds direct contracts with six of them.
Drayage
Short-haul trucking that moves a container between a shipper's facility and a rail ramp, or between a rail ramp and a consignee. The "first mile" and "last mile" of an intermodal move.
IMC (Intermodal Marketing Company)
A company that holds direct contracts with railroads and sells intermodal transportation services to shippers. Unlike brokers, IMCs have actual railroad contracts — giving them access to better rates and real capacity. LaserNet Jax is one of only 15 IMCs in the US with contracts across all Class I railroads.
Intermodal
The movement of freight using two or more modes of transportation — typically truck and rail — without handling the cargo when switching modes. The container stays sealed throughout the move.
Rail Ramp
Also called an intermodal terminal or ICTF. The facility where containers are loaded onto and lifted off of trains using large cranes. Ramp selection significantly impacts both cost and transit time.
53' Domestic Container
The largest domestic intermodal container, designed specifically for US rail and highway use. At 53 feet long and 9'6" tall, it matches a standard OTR 53' dry van trailer in cubic capacity, making it the most common container for domestic intermodal conversions from trucking.
40' Container
The standard international ISO container, also used widely in domestic and cross-border intermodal. Eligible for the East Coast Repositioning Program for westbound moves to LA, Oakland, Portland, Seattle, and Vancouver BC.
45' Container
A slightly longer ISO container offering more cubic capacity than the 40' while remaining compatible with international and cross-border rail moves. Also eligible for the East Coast Repositioning Program alongside 40' boxes.
OTR (Over-the-Road)
Traditional long-haul trucking where a single truck and driver move freight from origin to destination without using rail. The primary alternative to intermodal for long-haul lanes.
Repositioning Program
A railroad program that offers deeply discounted rates on lanes where equipment needs to be moved back to high-demand locations. LaserNet Jax participates directly in the East Coast Repositioning Program, moving 40' and 45' containers westbound at exceptional rates.
Transload
The process of transferring freight from one container type to another — for example, from an international 40' container to a domestic 53' container. Typically done at a rail ramp or warehouse facility.
TOFC / COFC
Trailer on Flatcar (TOFC) and Container on Flatcar (COFC) — the two methods of loading freight onto a railcar. COFC (stacking containers on flatcars) is the most common method in modern domestic intermodal.
Interline
A shipment that moves across two or more railroads during its journey. Most long-haul intermodal moves involve interline arrangements between connecting carriers. LaserNet Jax's direct contracts with multiple railroads simplify interline coordination.
Spot Rate
A one-time market rate for a specific shipment, as opposed to a contracted rate. Spot rates fluctuate with market supply and demand. IMCs with direct railroad contracts — like LaserNet Jax — typically offer more stable pricing than spot market rates.
