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.”
