Universal Machine Language Equipment Register (UMLER) is maintained by the Association of American Railroads through their Railinc subsidiary. UMLER is basically the registration of the title to a railcar or locomotive. UMLER registration is important to many functions in the railroad industry and to car and locomotive owners. UMLER data is used to show the mechanical construction and appurtenances on a railcar and compliance with rules and regulations such as air brake tests, etc. UMLER registration also demonstrates who the lessee, lessor and owner of the railcar or locomotive is which in turn demonstrates proof of ownership and financial securitization. Provided you are transferring UMLER from one owner to the next it is a fairly simple process which can be handled directly with Railinc.
