CBSMiami4报道，美国迈阿密当地搭乘Metrorail and Metromover systems的民众对电梯及自动扶梯维修期限过长、至今尚不能投入使用的情况怨声连连，而戴德县长称这是维修公司的商业模式转变造成的。每周都有数以万计的乘客达成轨道交通，而电梯及自动扶梯设备自从坏了以后就似乎一直没有恢复使用。迈阿密戴德县县长说：“县里有投入资金进行电梯维修，但合作的维修公司因为商业调整，减少了维修人员。我们以前可以同时请几家公司进行电梯维修的，但现在电梯公司说只有固定的某几个工作人员才能完成我们的电梯维修工作，还要等有充足的替换配件。”另一位官员说道，该县计划对轨道交通系统内的所有电梯设备都进行升级，把使用了30年以上的配件都换下来。
SLOW VT REPAIR VEXES MIAMI TRANSIT PASSENGERS
Riders of Miami's Metrorail and Metromover systems are lodging complaints about the slow progress on bringing broken-down elevators and escalators back into service, but the city's mayor said the problem was caused by changes in the business model of repair companies, CBSMiami 4 reports. Hundreds of thousands of people use the systems every week, but many say vertical-transportation (VT) equipment that goes down has tended to stay down for long periods. Miami-Dade County Mayor Carlos A. Giménez said the county has the money to repair the units, but VT companies have narrowed down who can make repairs. “The elevator companies have changed their business model. . . . We used to be able to hire different elevator repair companies to repair our elevators,” Giménez said, adding, “Now, elevator companies are saying only [certain] folks can repair our elevators, and they have to have our parts.” Another official said the county is planning to upgrade all of the systems' VT equipment to avoid problems "with replacing components that are 30 years old.”
