Inside Hitachi rail car assembly plant

If you’ve never darkened the doorway of a train manufacturing plant, it’s understandable to at first mistake Medley’s Hitachi facility for a contemporary art museum and the first three of 136 Metrorail cars being assembled there now to replace Miami-Dade’s fleet as a unique exhibit.

Everything in the airy 140,400-square-foot plant is spotless, from an elevated ceiling latticed with steel to a glossy concrete floor.

It’s quiet; the three cars in production seem artistically placed; and stairways leading to concrete pits, train tracks across the building and a north-to-south rolling platform to transfer cars out of the building onto a platform are equally pleasing to the eye.

Within a very short time, however, it’s clear the warehouse inside Miami International Tradeport is specialized for the sole purpose of train-car manufacturing and subassembly.

Owned by Hitachi Rail US, a subsidiary of one of the leading railway system suppliers, this is the Tokyo-based company’s first manufacturing facility in Miami and third in the US.

Miami Today joined county Transportation and Public Works Director Alice Bravo for a tour of the facility last week. Our guides included Mauro Melani, general manager of Hitachi Rail USA; Attilio Mirijello, logistics engineer at Hitachi Rail USA and site manager; Ralph Carl, an engineer and project quality manager; Ernest Matthews of the Transportation and Public Works Department, who oversees the project for Miami-Dade; and a few workers.

The custom-designed facility opened in March, said Mr. Melani, who pointed out features specifically for the assembly of heavy-rail metro including concrete pits. He said they were designed with two lines to accommodate work/testing of eight cars simultaneously to avoid bottleneck.

Once the facility begins operating at full production, Mr. Carl said workers will be completing six cars a month.

When the cars arrive in Medley, he said, they’re basically just metal shells. Prior to that, they’re made at a company called DRS Sustainment Systems in West Plains, MO, which has primarily defense contracts for military products and technologies for such uses as battlefield reconnaissance and surveillance.

“DRS has the two largest welding robots in the world building these shells for the company’s first municipal contract,” Mr. Carl said. “We get the shell and undergo the full assembly of all components: doors, electrical systems, wheel & axel assembly, install the rooftop HVAC and the under-frame equipment that takes the cars down the track.”

These first three cars, he said, are all the way to the water test stage to ensure they’re water tight. The cars will undergo a specified water pressure for a specified time at a large sloped pit with an enclosure containing 400 spray nozzles. Once tested and proven qualified to withstand the deluge of water Miami can bring, interior work will begin.

The new Metrorail cars will be roughly the size and length of those they’re replacing but with improved components, thanks to 40 years of technology.

“Riders won’t see a lot that’s different inside but they’ll certainly hear and feel vast improvements,” Mr. Matthews said. Technology has brought many changes since the county’s existing Metrorail fleet was built in 1984, including disc breaks that are essentially silent (compared with the screeching sound of tread breaks), computerized control of systems for  a smoother acceleration, reduced use of electricity and more reliability.

Also in the works now is development of a quality plan. Mr. Carl said the production people will sign off on the work they did; afterwards, the quality control people will do the same. “When the cars are complete, then the customer [Miami-Dade] says whether we’ve completed our function and follows up to make sure all specifications are met.”

The first three cars will be turned over to Mr. Matthews for “qualification” and go through strenuous testing, Mr. Carl said. Once criteria are established, the test will be set for the subsequent cars.

Mr. Mirijello said the entire workforce at Miami’s first railroad-making facility is local. Two-thirds of the 30-member staff is in the group assembling the cars now, while the other 10 are in management/administration. Once the plant is at full production, however, he said, about 120 workers from Miami-Dade will be producing the new Metrorail vehicles.

“We’ve found a lot of local workers have aerospace backgrounds,” Mr. Mirijello said. He’s in the plant for the eight hours the workers are Monday-Friday as well as some Saturdays, and is always there with Mr. Carl, who rarely works less than an 11-hour day.

All 136 cars are slated for delivery by 2019, with the first expected by the end of this year. Those first new Metrorail vehicles are anticipated to go into service in late 2017, after completing their testing.

    And yet Miami-Dade has put the kibosh on considering building future MetroRail extensions. Yes, MetroRail is expensive to build BUT it gets mass transit off the grid and into the air so traffic now and tomorrow will not be impeded– especially when a train breaks down. Surprised to learn that improved tech which is being used on the trains hasn’t transferred to the construction industry to make building the elevated tracks less expensive. Maybe it’s time to invite the Chinese to town to see if they can build more affordable concrete and steel extensions.

    It’s great to see manufacturing in Miami. Hope this will lead to other companies wanting to set up shop here. We’re too dependent on tourism anyway, and need greater economic diversification.

    Exactly DC could not state it better! Elected officials are corrupt!

    I also agree with DC! The Chinese have already built a light rail system in Ethiopia that makes our current metro rail look more obsolete.

    So MiamiToday takes a tour and that one photo is the best they can do? No wonder people read or Curbed over this paper.
