remains a bloated, highly political state corporation. For example, one U.S. rail official familiar with FNM estimated that two thirds of FNM's work force was redundant. Moreover, FNM's marketing is rudimentary and the impression is frequently conveyed to customers, by FNM sales personnel, that they have no choice but to deal with FNM. FNM's pricing tends to be based strictly upon the commodity type and distance, rather than actual costs. This system has contributed to the concentration of export traffic by rail through the Laredo/Nuevo Laredo gateway (estimated to account for 51.8 percent, Mercer Management Consultants). This gateway offers the lowest mileage, on FNM, from the U.S. border to Mexico City. In addition, the pricing system has resulted in a cross-subsidy from the long-distance routes from the U.S. border to the Valley of Mexico to higher cost portions of the system. Most notable among the high cost routes are those from the Gulf ports to Mexico City, which involve considerable switching and a climb of 7,000 feet. The cost differential is evidenced by the fact that trains from the U.S. border to Mexico City frequently have 90-to-100 cars, while those from the Gulf rarely, if ever, exceed 30 cars. One marine carrier speculated that some current and planned traffic using the Gulf Port would become uncompetitive, with overland rail routings, if the cross-subsidy problem were rectified. In a sense, the ongoing reforms have created problems within FNM's management. Recognizing the inevitability of outright privatization or concessions of major segments of the system or, at least, major reorganizations, many of FNM's best managers have gone to the private sector. Frequently, these individuals become consultants and middlemen for FNM or for U.S. carriers and shippers doing business with FNM.
