Systems and methods of insulating railcars
a technology of railcars and insulating systems, applied in heat-proofing, manufacturing tools, transportation and packaging, etc., can solve the problems of removing existing insulated railroad cars from service, not producing new replacements for these retired insulated railroad cars for at least 45 years, and achieving low cost, easy installation and removal, and improved thermal protection

Benefits of technology
This invention allows for the quick and temporary conversion of an uninsulated railroad car into an insulated car for the transportation of perishable or temperature-sensitive goods. By using magnets to secure insulation segments to the walls and ceiling of the car, the insulation can be easily installed and removed, and provide significantly better thermal protection for the goods. Overall, this invention provides a cost-effective and efficient solution for maintaining the temperature of sensitive goods during transportation.
Problems solved by technology
Over time, existing insulated railroad cars have been removed from service due to factors such as age and damage.
For various reasons, such as cost, new replacements for these retired insulated railroad cars have often not been produced.
It is believed that insulated railroad cars have not be commercially produced for at least 45 years.
This reduction in the number of insulated railroad cars in operation has placed a burden on companies that need to transport perishable goods by train.
However, these insulated containers require additional packing of the goods, may be expensive to replace when damaged, and often take up space reducing the amount of freight that may be transported in the railroad car.

Embodiment Construction
[0013]As stated above, conventional insulated railroad cars are becoming rarer as they are taken out of service and not replaced. The present invention provides systems and methods for insulating existing uninsulated railroad cars. As such, the present invention will be discussed below in reference to railroad freight cars that are described as either being insulated or uninsulated. As used herein, an insulated car is a freight car that is manufactured or otherwise equipped with insulation capable of protecting perishable or otherwise temperature-sensitive goods from temperatures outside the outer shell of the car, and the insulation takes the form of one or more layers of an insulation material, generally a foam material, that is typically permanently attached to interior surfaces of the outer shell and over which interior paneling may be applied to separate and protect the insulation material from the goods or containers thereof being transported within the car. In contrast, an un...

Abstract
Systems for and methods of insulating an uninsulated railroad car that include a plurality of insulation segments that are nonpermanently secured to interior surfaces of walls and a ceiling of the railroad car.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 898,303, filed October 31, 2013, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention generally relates to insulation materials. More particularly, this invention relates to systems and methods of insulating railroad cars of trains.[0003]There are many types of railroad cars each designed for transporting specific types of freight. In particular, perishable and other temperature-sensitive goods are generally transported in refrigerator cars or insulated cars. Whereas refrigerator cars have refrigeration equipment that maintain low internal temperatures, insulated cars rely on insulation to maintain the temperature of goods therein and provide protection from outside temperatures which may increase or decrease significantly during transportation. Conventionally, insulated railroad cars include an enclosed ...
