Citicorp Railmark, Inc. HO Scale Models

Citicorp Railmark, Inc., operating under the trade name Citirail Express and carrying the reporting mark CREX, is a locomotive leasing company with roots in the broader financial services operations of Citibank, itself a major division of Citigroup. The company was originally established on May 13, 1970, under the name Citicorp Aerolease, reflecting an initial focus on aircraft leasing before the enterprise expanded its portfolio into rail equipment. The transition into railroad equipment leasing represented a strategic diversification into a capital-intensive sector where financial institutions could generate steady returns by purchasing locomotives and leasing them to operating carriers on an as-needed basis. The locomotive leasing industry occupies an important niche in North American railroading, allowing carriers to supplement their owned fleets during periods of high demand, equipment shortages, or while awaiting delivery of new units from manufacturers. Companies such as Citicorp Railmark provide flexibility that would otherwise require railroads to maintain larger capital reserves or carry excess motive power during slower traffic periods. At one point, Citicorp Railmark assembled a fleet of approximately 167 locomotives available for lease to various railroad customers across the continent. Over time, the company substantially reduced its locomotive holdings, selling or otherwise disposing of the majority of its fleet through sales and lease arrangements, eventually retaining reportedly only a single unit. This contraction mirrors broader shifts in the rail leasing market, where larger and more specialized lessors have come to dominate the field. Despite its reduced operational footprint, Citicorp Railmark remains a subsidiary of Citibank and continues to represent the financial sector's longstanding interest in railroad equipment as an asset class.
