Unit trains are more efficient because they can deliver a single product to one place, rather than delivering one product at one city and another product at a different city.
Unit trains leave one city and end at a second without any stops for switching cars in or out of the train.
Freight trains have been around for a long time, but the modern trains we have today can do much more. Unfortanutly, I do not have the answer, but good luck on your report.
To move freight and passengers. believe it or not trains move more ton-miles than trucks.
Automobiles are more convenient than trains for most people. One must get to the rail station and get there when the train is there. As train traffic declined, railroads ran fewer trains and serviced fewer towns. This lead to still greater decline, Passenger trains also compete with freight trains. If railroads make more money on freight, they were will slight the passenger service in favor of hauling freight.
A freight train or goods train is a group of freight cars (US) or goods wagons (UIC) hauled by one or more locomotives on a railway, ultimately transportingcargo between two points as part of the logistics chain. Trains may haul bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars.
It really depends on what they are hauling and length. The most popular in my area (East TN & KY) are 95 - 105 car coal trains weighing in around 13,500 - 15,500 Tons + 2-4 engines sometimes more (wide bodies weigh I think around 200 tons each). In some areas they can be 130 or more cars weighing I'm guessing 18,000 - 20,000 tons + 4-6 sometimes 8 engines. Intermodal trains are typically longer but weigh considerably less. Mixed freight trains vary greatly in length and weight but also weigh less than coal trains. I do not have any experience with passenger trains someone else will have to post that information.
The motto of ABF Freight System is 'Expect More'.
There are a number of truck freight companies situated in Texas. A few of these are Texas Freight, Dixie Freight and Fast Freight Services. Had one wanted to search a freight companies website for more options, one could visit Freight Center.

Toy trains are more popular in the United States.
Freight rates are detemined by the company, usually based on the distance the package needs to travel, the speed (air freight is more expensive than road freight is more expensive than sea freight) and customs/border issues. Often there's also a part of the fee set aside for insurance.
The height of the bridge was to low for the freight on the truck to pass under. When rail transportation was at its height, it handled more freight than trucks did.
